Christina Parcell's Sister

Appearances

20/20

The Rose Petal Murder

1003.588

I can only think of one person in the world that I would instantly think of would have interest in seeing my sister murdered.

20/20

The Rose Petal Murder

1022.99

In the aftermath of Christina Parcell's murder, it's her sister, Tina, who's left to tell her nine-year-old niece the tragic news. So you had to tell her that her mother was dead? Mm-hmm. She wailed.

20/20

The Rose Petal Murder

1040.348

And she was inconsolable sobbing. I told her there had been an accident. Mommy had been hurt very, very badly and she died. She didn't make it. And her response was, who did it?

20/20

The Rose Petal Murder

1058.1

When police talk to Christina's fiance, Bradley Post, after the murder.

20/20

The Rose Petal Murder

1063.961

He immediately brings up somebody he thinks should be a person of interest. So you asked him, do you know who would do this?

20/20

The Rose Petal Murder

1100.594

John Mello says he's a music producer. He met Christina in 2004. He was a 43-year-old married father of two. She was 24. Both cameras have it? Yep. All good? So I guess let's start at the beginning. How did you come to meet Christina?

20/20

The Rose Petal Murder

111.393

It makes utterly no sense.

20/20

The Rose Petal Murder

1143.824

Were you trying to have a relationship?

20/20

The Rose Petal Murder

1160.395

At what point did it become a romantic relationship?

20/20

The Rose Petal Murder

1174.558

Mello and Christina dated for the next six years. So you had a discussion, decided you were going to try to have a baby? Yes, yeah, planned it. That's a little surprising to me, because you were married.

20/20

The Rose Petal Murder

1198.112

But while things were going well with the new baby, by then Christina had become estranged from her sister and the rest of her family.

20/20

The Rose Petal Murder

1206.979

Between April and May of 2010, my sister cut off ties with our whole immediate family. She sent a letter to my parents, addressed it to all of us. She had been with John for a year when she sent this. She was being increasingly cut off from the world around her. So when you started to talk to her again, how did she explain that letter? It's what John wanted.

20/20

The Rose Petal Murder

123.779

This was the manifestation of hate.

20/20

The Rose Petal Murder

1246.144

The estrangement would last over four years.

20/20

The Rose Petal Murder

1249.505

When she came back to our family, I mean, we found out she had a daughter. My niece was more than two when I met her the first time.

20/20

The Rose Petal Murder

1258.91

By the time the child was three years old, relations between Mello and Christina were breaking down. So at some point, you guys end up in kind of a tough custody battle.

20/20

The Rose Petal Murder

1297.389

In 2016, Mello is granted sole custody. Christina, just visitation. In court documents, Mello describes what he calls her erratic behavior and lack of consistent visitation, while Christina says she's afraid of Mello and doesn't earn enough money to support her daughter.

20/20

The Rose Petal Murder

130.273

We've come here to this quiet suburban street in South Carolina to cover one of the strangest crime stories we've ever come across. It's a story of love, betrayal, classical music, murder, a crime scene strewn with rose petals. And it all began at this house on an October morning in 2021 with a 911 call. Greifel County 911, what's the address of your emergency?

20/20

The Rose Petal Murder

1324.608

In the years that follow, Mello repeatedly contacts law enforcement and the Department of Social Services about Christina, accusing her of prostitution, drug use, and even child sex abuse.

20/20

The Rose Petal Murder

1361.584

In the course of their custody battle, Mello is arrested and charged with stalking and then harassment, accused of repeatedly making unfounded accusations against Christina. Both charges are ultimately dismissed.

20/20

The Rose Petal Murder

1391.505

It's 2018 when attorney Maggie Bailey gets a visit from Christina.

20/20

The Rose Petal Murder

1416.901

I got specifically a three bedroom apartment so she and my niece could stay with me and we could spend time together, go to the pool, go to the playground.

20/20

The Rose Petal Murder

1436.936

But then, in October 2020, the custody fight takes another explosive, and for Christina, terrifying turn.

20/20

The Rose Petal Murder

1445.524

It was time for her visit weekend, and John said, we won't be back in time. I'll call you when I know more.

20/20

The Rose Petal Murder

1452.236

His message reads, we are out of the country, phone not working. Be advised, we won't be able to fly back for Friday exchange.

20/20

The Rose Petal Murder

1470.356

My sister reached out to the elementary school and found out John had withdrawn her from Greenville County School System. She messages Mello, please tell me anything you can about where our daughter is. I'm scared.

20/20

The Rose Petal Murder

1643.922

For Tina Parcell and John Mello, there's not much room for agreement except on one thing, the strangeness of those red roses found at the crime scene.

20/20

The Rose Petal Murder

1669.097

Tina even keeps an eye out for a special delivery at her sister's funeral.

20/20

The Rose Petal Murder

1674.7

I had the funeral home hold every flower delivery so I could inspect them to make sure no red roses were sent because I fully expected some to be sent. Why? because that would be a mean and cruel thing to do. And let's just be honest, mean and cruel kind of fits the whole bill for the situation.

20/20

The Rose Petal Murder

1692.988

For her, the roses add to her suspicion of John Mello. She tells investigators what happened a year earlier. In 2020, the custody battle between Christina Parcell and John Mello had become an outright war after he took off with their eight-year-old daughter. Christina has no idea where she is and frantically searches social media for clues.

20/20

The Rose Petal Murder

1716.07

She just pored over the internet, looking for everything, doing all kinds of searches. And then Mello emails Christina. Please do not bother people about us saying their daughter is doing great. She is happy and healthy. It's just a new setup. That's all new rules.

20/20

The Rose Petal Murder

1770.894

She was inconsolable. She couldn't sleep. She couldn't eat. She called county police. She called the FBI. She called the State Department.

20/20

The Rose Petal Murder

1781.676

Mello claims he took their daughter to Italy to protect her from her mother.

20/20

The Rose Petal Murder

1806.51

So when you went to Italy with your daughter, did you think that you were breaking any laws? Absolutely not.

20/20

The Rose Petal Murder

1843.975

She found out they scheduled a hearing at essentially the equivalent of family court in Italy. And I asked her, do you want me to go with you? And she said yes. So I instantly bought us two round trip tickets.

20/20

The Rose Petal Murder

1859.096

This is video from their hotel room from the day before the hearing. Christina is on the bed.

20/20

The Rose Petal Murder

1879.067

The court rules that Mello violated Christina's custody rights, even if limited, and acted against their daughter's interest. It's a victory for Christina, six months after Mello took their daughter out of the country.

20/20

The Rose Petal Murder

1905.757

John Mello stays in Italy while Christina heads back to South Carolina with their daughter.

20/20

The Rose Petal Murder

1922.767

I took her to the playground.

20/20

The Rose Petal Murder

1924.144

But just three months after the joy of being reunited, Christina Purcell is blindsided again.

20/20

The Rose Petal Murder

1943.669

It's not just her attorney who has received the mailing. The photos were sent to our house, Post's house, all of our neighbors, all of his neighbors, Christina's work, the guardian ad litem.

20/20

The Rose Petal Murder

2016.143

John Mello says he didn't arrange for the mailings to be sent out. Did you have those images mailed?

20/20

The Rose Petal Murder

2056.171

Two and a half months after the mailings were sent, Christina Purcell is murdered. But it turns out the man so many people seem to suspect could not have been the killer.

20/20

The Rose Petal Murder

2092.73

And then, a huge turning point in the case, thanks to a neighbor's ring camera.

20/20

The Rose Petal Murder

2107.332

And a shocking arrest. But it's not what you think.

20/20

The Rose Petal Murder

2120.285

Police are investigating Christina Parcell's murder. Her fiance, Bradley Post, tells them he's convinced John Mello, despite being in Italy, should be the prime suspect.

20/20

The Rose Petal Murder

2137.391

Although authorities have their suspicions about Bradley Post himself, their investigation seems to be pointing away from him.

20/20

The Rose Petal Murder

2196.509

Even though he expresses some nervousness, Post continues to work with police.

20/20

The Rose Petal Murder

2210.29

But then investigators stumble upon what they claim is evidence of an entirely different crime.

20/20

The Rose Petal Murder

2249.869

According to court documents, Post had a high volume of child pornography on his phone and electronic devices. He has not yet entered a formal plea to those charges.

20/20

The Rose Petal Murder

2272.205

So although Bradley Post is now facing some serious charges, police still don't think he's the person who killed Christina Parcell. And they now have a critical clue in the hunt for who did. As you start to go looking for evidence, what's the first thing that you do outside of the home? Cameras. Cameras. So where were the first cameras that you found?

20/20

The Rose Petal Murder

2300.72

The camera is from the house directly across the street from where Christina Purcell lived. And so you get that camera. What do you see on that camera?

20/20

The Rose Petal Murder

2333.806

So if that vehicle hadn't driven by at that moment, you wouldn't have seen who walked in the house.

20/20

The Rose Petal Murder

2404.682

The Ring camera offers another important development. While investigators don't know who the mysterious man is, they are now confident of who it isn't.

20/20

The Rose Petal Murder

241.101

Master Deputy Chris Robinson rushes to the scene. He's the first to arrive.

20/20

The Rose Petal Murder

2433.069

The next order of business, finding the man on the bike.

20/20

The Rose Petal Murder

2446.203

Turns out the man on the bike will not remain a mystery for long.

20/20

The Rose Petal Murder

2457.093

Police zero in on somebody you'd never expect. Will this finally explain the crime and those odd rose petals?

20/20

The Rose Petal Murder

2484.71

the manifestation of hate wrought upon a physical body.

20/20

The Rose Petal Murder

2498.541

You don't think Zach is a killer?

20/20

The Rose Petal Murder

2509.106

It makes utterly no sense.

20/20

The Rose Petal Murder

2514.169

Instruct him to be quiet.

20/20

The Rose Petal Murder

2518.953

How is that not murder?

20/20

The Rose Petal Murder

2523.695

Either you had some part of this, or you were caught in the craziest murder case that any of us have ever heard of.

20/20

The Rose Petal Murder

2558.663

After Christina Parcell is stabbed to death in the house she shares with her 9-year-old daughter and her sister Tina, investigators piece together camera footage from around their neighborhood that provides critical details about the person who did it.

20/20

The Rose Petal Murder

258.05

So when you pulled up, was he just like standing there waiting for you?

20/20

The Rose Petal Murder

2614.246

With Bradley Post and John Mello ruled out as the killer, investigators are working overtime to figure out who the man on the bike is.

20/20

The Rose Petal Murder

2636.863

Given John Mello's solid alibi, investigators decide to dig a little deeper into his circle of friends and acquaintances.

20/20

The Rose Petal Murder

2668.472

Like Bradley Post, Michael Manigault does not match the ring camera footage of the man recorded entering the Parcell house.

20/20

The Rose Petal Murder

2683.444

But when investigators ask Manigault what he knows about Christina's death, he gives them a new name.

20/20

The Rose Petal Murder

2721.229

The videos are from a virtual concert series Hughes did with a local museum and posted on his YouTube channel.

20/20

The Rose Petal Murder

2768.703

Investigators discover a crucial clue not far from downtown Greenville. If you look up there, you'll see a camera. That's called a flock camera. It's an automated license plate reader that alerts law enforcement if a wanted vehicle is detected.

20/20

The Rose Petal Murder

2874.574

Investigators don't have enough yet to make an arrest, so they let Zach Hughes go, but not before obtaining a sample of his DNA.

20/20

The Rose Petal Murder

2893.067

While they wait for the DNA results, authorities are trying to determine just how close Zach Hughes and John Mello really are. How did you come to know Zach?

20/20

The Rose Petal Murder

2943.148

Mello says that once he takes his daughter to Italy, he loses touch with Hughes for a few months. But after Christina Parcell wins her case to bring their daughter back to the United States, he says the two men reconnect.

20/20

The Rose Petal Murder

2964.202

You don't think Zach is a killer?

20/20

The Rose Petal Murder

2974.025

Even while investigators are zeroing in on Hughes, prosecutor Walt Wilkins has the same question.

20/20

The Rose Petal Murder

30.049

This was a slaughter. Make no mistake about it. And what did you find when you got inside?

20/20

The Rose Petal Murder

3089.381

You know, a lot of people don't know who he is and kind of what his background is. How did he end up in Greenville?

20/20

The Rose Petal Murder

3124.246

Like when you say good at it, like prodigy good?

20/20

The Rose Petal Murder

3199.887

As seen here in a video posted on YouTube, Zach Hughes graduates from Juilliard in 2015. He spends a season with the Knoxville Symphony Orchestra before eventually settling in Greenville, South Carolina amid its thriving local arts and music scene.

20/20

The Rose Petal Murder

3240.199

Zach Hughes posted videos of the Beethoven Odyssey on his YouTube channel.

20/20

The Rose Petal Murder

3289.417

During the COVID pandemic Zachary Hughes could often be found here in downtown Greenville with his keyboard sharing his Juilliard training and his love of Beethoven with the community.

20/20

The Rose Petal Murder

3314.94

That man, of course, is John Mello. And this chance encounter is the start of their friendship.

20/20

The Rose Petal Murder

3325.12

It was in May of 2021. Zach actually goes to Italy to visit John Mello. What's that trip about?

20/20

The Rose Petal Murder

3357.771

Cemented by the time in Italy, their connection continues when Zach Hughes returns home to South Carolina.

20/20

The Rose Petal Murder

3376.998

But investigators are starting to believe that Zach Hughes did, in fact, meet Christina Parcell on at least one occasion. And they say they've now got the evidence to prove it.

20/20

The Rose Petal Murder

3430.967

And at a bond hearing for Zach Hughes, the courtroom is packed with supporters insisting that he's not capable of murder.

20/20

The Rose Petal Murder

3472.788

Ultimately, the judge denies Hugh's bond, and now it's up to the state of South Carolina to prove to a jury that this 29-year-old piano virtuoso is also a cold-blooded killer.

20/20

The Rose Petal Murder

3491.403

And prosecutors now think they have evidence implicating Mello in the murder. There was a text exchange between you and Zach where you ask him, how's the music research going?

20/20

The Rose Petal Murder

3503.032

On the day of the murder.

20/20

The Rose Petal Murder

3509.017

So were the men discussing music or murder? Three years after Christina Parcell's murder, Zachary Hughes' trial begins. Family and friends pile in here to the Greenville County Courthouse to see if this accomplished musician might also be a killer.

20/20

The Rose Petal Murder

3567.697

One of the first witnesses to take the stand clad in an orange jail jumpsuit is Christina Parcell's fiancee, Bradley Post. Prosecutors want to ask him about that morning he found her dead.

20/20

The Rose Petal Murder

3592.449

Prior to the start of the trial, the judge ruled that jurors would not be allowed to hear that investigators had allegedly found a high volume of child pornography on Post's electronic devices, or that he was facing charges of sexual exploitation of a minor.

20/20

The Rose Petal Murder

3641.888

The medical examiner testifies to just how violent the attack appeared to be.

20/20

The Rose Petal Murder

3669.835

Next, a court-appointed attorney for the child in the custody dispute takes the stand to address the conflict that prosecutors say is at the heart of this case.

20/20

The Rose Petal Murder

3701.474

At the time of the murder, remember, John Mello was still in Italy. And that, prosecutors say, is why Mello needed Zach Hughes.

20/20

The Rose Petal Murder

3738.356

But because Zach Hughes had deleted those encrypted WhatsApp messages before authorities got his phone, when they were able to retrieve them, they came back scrambled.

20/20

The Rose Petal Murder

3778.049

When I spoke to John Mello prior to Zach Hughes's trial, he told me about sending this message.

20/20

The Rose Petal Murder

3797.284

But prosecutors argue at trial this is when John Mello convinced Zach Hughes to help him in that alleged campaign of harassment against Christina, sending those explicit photos from a supposed escort website.

20/20

The Rose Petal Murder

380.268

And what could you see happened?

20/20

The Rose Petal Murder

3833.049

The most significant communication between the two men, prosecutors say, was their last WhatsApp message sent just hours after Christina Parcell was killed.

20/20

The Rose Petal Murder

3862.537

There was a text exchange between you and Zach where you ask him, how's the music research going?

20/20

The Rose Petal Murder

3869.444

And some people think that could be code for how did the murder go?

20/20

The Rose Petal Murder

3889.434

But prosecutors have one more damning piece of evidence against Hughes to put before the jury.

20/20

The Rose Petal Murder

3913.868

With the state's case laid out, it's now the defense's turn. And in a twist, they announce Zach Hughes will be taking the stand.

20/20

The Rose Petal Murder

3927.317

And what he tells the jury catches prosecutors and just about everyone else in the courtroom off guard.

20/20

The Rose Petal Murder

3942.321

Why did you feel like it was important for you to be there? Part of me feels like by being there every day, every minute of this trial, maybe she got to be there too. Courtroom 8 got fuller and fuller as days went on. So we're standing outside the courtroom right now. It has been quite a sight, to say the least.

20/20

The Rose Petal Murder

397.594

Could you tell that it was a stabbing or a shooting?

20/20

The Rose Petal Murder

3970.532

Zach Hughes' defense team opens with a bombshell, announcing not only will Hughes take the stand, but he's prepared to confess to killing Christina Parcell.

20/20

The Rose Petal Murder

4003.738

Hughes first describes how he met John Mello and learned the details of the contentious custody battle that Mello was in with Christina. He says Mello told him that he was worried for his daughter's safety. And in an attempt to help, Hughes admits he was the one who mailed those envelopes with the explicit pictures of Christina.

20/20

The Rose Petal Murder

4046.335

I'm curious why the concern for this child, a child that he doesn't really know that well.

20/20

The Rose Petal Murder

407.358

Was there anything else about that room that seemed odd to you?

20/20

The Rose Petal Murder

4139.321

According to Hughes, those roses found at the scene that caused so much speculation were nothing more than a ruse. And along with the flowers, he also had a gun.

20/20

The Rose Petal Murder

419.044

And then you came back outside.

20/20

The Rose Petal Murder

4209.016

Zach Hughes says that he knew he didn't have time to clean up all of the now scattered rose petals.

20/20

The Rose Petal Murder

4238.712

The paint thinner Hughes brought with him explains that odd smell the responding officer noticed. That's true. But even after his detailed testimony, Zach Hughes' defense attorneys insist that he is not guilty of murder.

20/20

The Rose Petal Murder

4270.923

He planned this. He had a gun and a knife. He basically lied to get into the home, and then he stabbed this woman. How is that not murder?

20/20

The Rose Petal Murder

4289.221

And the defense had argued that there were serious abuse allegations against Christina Parcell herself and that jurors should hear them. The judge ruled those accusations were irrelevant and inadmissible, but that didn't stop Zach Hughes from repeatedly making them during his testimony.

20/20

The Rose Petal Murder

4358.352

Investigators say it's also important to note that nobody knew of the allegations against Bradley Post until his arrest after Christina Parcell's murder.

20/20

The Rose Petal Murder

4385.346

But Zach Hughes' testimony isn't over yet. And there's one more bombshell to come.

20/20

The Rose Petal Murder

446.914

Christina Parcell, a single mother of one who police quickly discover has not been shot, but has been stabbed 35 times.

20/20

The Rose Petal Murder

4467.56

In this Greenville County courthouse, classical pianist Zach Hughes has a rapt audience as he takes jurors step by step through how he says he killed Christina Parcell.

20/20

The Rose Petal Murder

4496.282

And if a confession from the witness stand wasn't shocking enough, Hughes drops another bombshell, testifying that his friend and Christina Parcell's ex, John Mello, offered to pay him on two separate occasions to kill her.

20/20

The Rose Petal Murder

4543.14

We reached out to John Mello about these allegations right after Zach Hughes's testimony. And he told us, quote, it never happened.

20/20

The Rose Petal Murder

4569.767

Before he made the decision to do this, did he have any physical proof that this child was in harm's way.

20/20

The Rose Petal Murder

4587.866

Zach Hughes says he also had the chance to see Christina's daughter while he was visiting John Mello in Italy, and Mello spoke to her over Zoom.

20/20

The Rose Petal Murder

4608.623

Now, after a full day of testimony, it's the prosecutor's turn to question Zach Hughes.

20/20

The Rose Petal Murder

4732.455

The case is now in the hands of the jurors, one of whom was this man, David Collins.

20/20

The Rose Petal Murder

4753.642

After less than three hours of deliberations, the jury returns with a verdict.

20/20

The Rose Petal Murder

477.762

Lead investigator Jared Sparkman arrives to the scene shortly after Deputy Robinson. When you pull up to the scene, what do you see?

20/20

The Rose Petal Murder

4782.0

Before sentencing, Zach Hughes' father speaks to the court.

20/20

The Rose Petal Murder

4823.364

The question now, will John Mello be the next person charged in this case? Are you worried they're going to arrest you in connection with this murder?

20/20

The Rose Petal Murder

4840.655

Zach Hughes's unexpected courtroom testimony has now put the spotlight back on John Mello, prompting investigators to take action.

20/20

The Rose Petal Murder

487.387

Describe to us this crime scene.

20/20

The Rose Petal Murder

4884.707

You did this to your family. Your child has to know that you did this.

20/20

The Rose Petal Murder

4897.466

When I sat down with John Mello before Zach Hughes' trial, I asked him about the allegations swirling around him that he was somehow involved in this murder. Are you worried they're going to arrest you in connection with this murder?

20/20

The Rose Petal Murder

49.235

Now, the stunning court case making big headlines. When's the last time you talked to your sister? She was gone.

20/20

The Rose Petal Murder

4926.667

But either you had some part of this, or you were caught in the craziest murder case that any of us have ever heard of.

20/20

The Rose Petal Murder

4951.804

We reached out to John Mello's attorney, but he declined to answer our questions and says he looks forward to his day in court. Mello has not yet entered a formal plea to these charges. Do you think in some ways that Zach was manipulated by John Mello?

20/20

The Rose Petal Murder

4978.237

There should be justice. People should be held accountable for their actions, for willfully, willingly, cruelly hurting people in this world, whether you know them or not, whether they're family or not, whether you love them or not.

20/20

The Rose Petal Murder

5007.102

And at the center of this tragedy, an innocent little girl left without her mother. Christina's daughter has been temporarily placed with friends of John Mello upon his request, following a family court ruling. Her aunt Tina is currently fighting for custody of her.

20/20

The Rose Petal Murder

5031.525

The same thing I've always wanted for her. My job is for her to be safe, healthy, and happy, specifically in that order. She deserves better than this.

20/20

The Rose Petal Murder

510.791

People think of stabbings as really intimate, right? Did this seem like a fight, like this was a crime of passion?

20/20

Never. I remember every bit of it now. She had a job interview that morning. She was trying to find a job with more hours, better pay. Did you see her that morning as she was getting ready for it?
