28 Feb 2026

Transcription

Chapter 1: What is the main topic discussed in this episode?

0.031 - 9.524 Matthew Wilson

Is this on? Season 3 of Proof, Murder at the Bike Shop, is available now, wherever you get your podcasts. I'm scared to be sitting here in this damn chair talking about this shit.

10.144 - 18.135 David Muir

This is a guy confessing a murder to her, and she has no idea what day it happened. Everything I tell you is the truth. I hope I don't bring a ton of shit down on me.

0

18.736 - 26.046 Matthew Wilson

Listen to Season 3 of Proof now, wherever you get your podcasts. There was evidence in the house, and they would not listen to me.

0

26.967 - 29.43 Barbara Wilson

It's not me. I didn't do it.

0

33.865 - 41.493 David Muir

It was a cool evening. Of course, the city was getting into the holiday spirit at that time.

43.475 - 49.322 Sean Ayers

Amy was going to the mall with Sarah, and Jennifer went to work at the yogurt shop.

50.864 - 82.413 David Muir

We believe that it was business as usual. The shift started about 7 o'clock. It was set to close around 11 PM. Two of the girls had left to go to the mall and were coming to the yogurt shop. They were going to have a big slumber party, a big sleepover. It's Friday night. They're wanting to get out of there. The girls were all picking up, cleaning up the yogurt store.

84.115 - 88.881 David Muir

Something horrific and evil was about to walk in that door.

89.603 - 111.915 Matthew Wilson

They were supposed to be home by 11, but they were already dead by 11. 2J, Wednesday 21, 10-28.

Chapter 2: What happened during the tragic yogurt shop murders in Texas?

257.293 - 280.708 David Muir

They were burned too much. As soon as the Austin Police Department realized the scope of what they were dealing with, they called in extra investigators to help them. Specifically, the FBI arrived at the scene, the ATF arrived at the scene. It was an uphill battle to begin with, the processing of that crime scene. Everything gets doused with water.

281.769 - 305.717 David Muir

Because they did such a good job in putting the fire out, a lot of our evidence was destroyed. There was evidence of sexual assault at the crime scene on the victims as well. So all four girls were nude, and their clothing had been used to tie each other up. They also took DNA from those victims.

0

306.478 - 329.529 David Muir

So part of your standard sexual assault kit at an autopsy, besides swabs, is you also would take fingernail clippings. For that very reason, because you think if a woman's being sexually assaulted, there's a good chance she's going to fight back. And the fact that we were able to get any DNA and any evidence from this scene is pretty remarkable, especially given the year, 1991.

0

330.09 - 365.026 David Muir

DNA really was not something we talked about back then. Initially, it was thought that it was possibly a robbery gone wrong, a robbery that turned into a horrific murder because cash had been pulled out and there was some cash missing. We're dealing with four beautiful teenage girls. Two of them are sisters, Jennifer and Sarah Harbison, Amy Ayers, and Eliza Thomas. Just beautiful girls.

0

365.947 - 401.051 David Muir

And it's just a tragedy. These girls were so innocent, enjoying their high school years and their friendships. and just having a really good time that night together. So Eliza Thomas and Jennifer Harbison were working the evening shift that Friday night. It was set to close around 11 p.m.

401.692 - 424.896 David Muir

But two other girls, Jennifer's sister, Sarah Harbison, as well as her dear friend, Amy Ayers, they were at the mall earlier that evening but went to the yogurt shop. They were going to have a big slumber party, a big sleepover. They've swept, they've mopped, they've cleaned the yogurt machines, put napkins in the napkin holders, all that good stuff.

425.922 - 456.458 David Muir

The girls were doing what they do every time they shut the shop down. They were putting the chairs up on the tables. They were taking the money out of the cash register. The girls were herded into the back of the shop where they were forced to strip. They were forced to tie each other up with their underclothes, bound and gagged. They were sexually assaulted.

457.46 - 480.963 David Muir

And then they were each shot in the back of the head, execution style. And the place was set on fire. So all four girls were shot with a .22. And then Amy, the youngest victim, was also shot a second time with a .380 semi-automatic pistol. And that shell casing actually made its way into the floor drain.

486.089 - 515.656 David Muir

The fact that Amy had a .380 and a .22, that she was shot by two different weapons, still remains a very intriguing piece of this case. Logically, you'd think two people, or at least two people. Why would you have two guns? So that was the working theory that it was more than one person. It was a very limited amount of resources back in 1991 to devote to this case.

Chapter 3: How did the police respond to the discovery of the crime scene?

702.37 - 706.276 Matthew Wilson

I see Shawn holding her when she was a baby. He wanted a sister.

0

708.3 - 716.192 Detective John Jones

I mean, that was the first time I got to hold her. So it's like that's when I became a big brother.

0

717.337 - 720.903 Sean Ayers

She had strawberry blonde hair, about the length of mine.

0

722.605 - 725.73 Matthew Wilson

And she wore a hat, a straw hat in the summer.

0

728.515 - 741.876 Detective John Jones

We were joined at HIPP. And she'd go out with me to take care of the animals. And we were always riding together. And she was just a cowgirl.

747.104 - 757.118 David Muir

So in December 1991, it was a cool evening. Of course, the city was getting into the holiday spirit at that time.

760.162 - 769.095 Matthew Wilson

Amy was going to the mall with Sarah, and Jennifer went to work at the yogurt shop, and then they were going to go home to Sarah and Jennifer's house.

771.573 - 782.525 Sean Ayers

I remember the doorbell ringing and I looked out the bedroom window and saw police cars. I told him, I said, the police are here. And we went to the front door.

782.565 - 786.156 Detective John Jones

This all started at 5.30 in the morning.

Chapter 4: What evidence was found at the yogurt shop crime scene?

1672.664 - 1679.414 David Muir

There was a huge effort to try and solve the crime. We know all there is to know, you know, about the, you know, about the crime itself.

0

1679.914 - 1698.745 Detective John Jones

And we've got, you know, everything ready except who to charge with. It was a fight. We got excuses like, well, there's more homicides happening every day in Austin. I said, that's fine. But, you know, just keep working on this one.

0

1698.765 - 1727.401 David Muir

Despite all efforts, there are no major breakthroughs, and more importantly, there are no arrests. In the late 1990s, there was a new effort to try to solve this crime. Investigators dust off the old files. They take a new, fresh look at the evidence and wind up going all the way back to square one. 33 boxes of evidence and videotapes and audiotapes and things.

0

1729.003 - 1751.142 David Muir

The police were drawn to the fact that these four original suspects, Maurice Pierce, Forrest Wellborn, Michael Scott, and Robert Springsteen, were all involved in this. They bring in Michael Scott and Robert Springsteen for interviews and interrogations.

0

1751.202 - 1755.787 Matthew Wilson

What we're going to be talking about today is kind of taking you back to 1991.

1756.929 - 1781.059 Detective John Jones

I'll be honest with you guys, I have a piss-poor memory. Well, and one of the reasons that we're here is to help you try and remember. We're just kind of going back over things and trying to do the best we can and kind of talk to people that I really want to talk to that well. Why don't you tell us a little bit about yourself?

1781.079 - 1791.268 David Muir

They were interviewed over and over and over again. Michael Scott and Robert Springsteen were subjected to 18 hours and five hours of interviews, respectively.

1792.069 - 1802.318 Matthew Wilson

This is where the case takes a major turn.

1803.935 - 1837.916 David Muir

Michael Scott indicates that he and the other three boys were in fact involved in these horrific murders. He said that Maurice Pierce was something of the ringleader of the crime, Forrest Wellborn was the lookout, and that he and Robert Springsteen were the primary offenders in terms of killing the young victims and robbing the store. Boris Welburn and Maurice Pierce never confess to the crime.
