However, no one could ignore the fact that the circumstances of the crime were strikingly similar to what had happened to Lisa and Brandon nearly seven months earlier.

But the Yavapai County Sheriff's Office was very quick to stamp out any suggestion that the cases were connected.

Detectives stated to the press that they did not believe the crimes were linked.

And really, it seemed like that was that, because several more months passed before any kind of update came in with regards to Lisa and Brandon's case.

Tony Laxon reported for the East Valley Tribune that in mid-August 2004, 10 months after the couple's murders, law enforcement investigators and representatives from the Silent Witness program released a videotaped reenactment of the crime in hopes of enticing additional witnesses to come forward.

A sergeant with the sheriff's office told the press that detectives suspected there were still some witnesses out there who had yet to provide information to authorities.

The sergeant wasn't sure why those witnesses had not come forward yet, and waiting for answers was painstaking for the victim's families during this time.

Paula, Lisa's mom, said that she thought about the case every single day, and she hoped that whoever was responsible would be captured.

Her hopes were seemingly raised right after that, when information about another young couple slain at random while camping in Northern California made national news.

Those victims were Lindsay Cutshall and Jason Allen, whose case I covered in a previous episode of Park Predators titled The Sand.

Because Lindsay and Jason's shooting deaths happened under similar circumstances, investigators working their case initially considered whether their deaths might be linked to whoever had killed Lisa and Brandon.

Jason and Lindsay were murdered execution-style while they slept in their sleeping bags on a beach.

Lisa and Brandon were killed in an eerily similar manner, but just in a desert environment.

No signs of robbery or evidence like shell casings were found at the California crime scene, as was the case in Arizona.

But as quickly as investigators in California contacted Yavapai County authorities to compare notes, the lead fizzled.

The caliber firearm used in the California case was different than the type of gun that had been used to kill Lisa and Brandon.

And ultimately, as you already know if you listened to my episode about Lindsay and Jason's case, their killer was later caught and identified as Northern California native Sean Gallen.

So the double homicides are for sure two totally separate unrelated crimes.

When the one-year anniversary of Lisa and Brandon's murders rolled around, it was a benchmark that Paula Guerreri was not looking forward to.

She drove out to the spot in the desert where her daughter and Brandon were murdered, but she still had no answers about who had carried out the crime.
