Case Overview
Jamie Laity, a vibrant and independent woman, vanished in March 2010 from Phoenix, Arizona. Her disappearance puzzled friends and family, especially given her respected standing and close-knit social circle. The episode meticulously traces Jamie's last known months, revealing her growing isolation and the strains in her relationship with Brian Stewart.
- Gwyneth Newman reflects on the personal impact:
"Jamie lost. We don't know where she is and it's really sad. She was a good person and she didn't deserve this." (00:00)
Disappearance and Initial Signs
Jamie moved to Phoenix post-graduation to carve out her own identity. Despite her success in a high-paying job, the economic downturn in 2009 led to her unemployment, causing significant distress.
- Brian Stewart expresses concern:
"I believe Jamie was murdered because there's no clear explanation as to where she is now, what happened to her..." (02:55)
Jamie became increasingly reclusive, and her friends initially overlooked her absence, attributing it to her desire for privacy.
- Gwyneth Newman shares her disbelief:
"I think people were just respecting her privacy and her space. And that was unfortunate." (11:18)
Investigation Unfolds
Marlena Buffa, the president of Jamie's University of Michigan alum club in Phoenix, became suspicious when Jamie failed to show up, prompting her friends to hire a private investigator, Burke Files. Their investigation revealed unsettling details about Brian Stewart's past, including his association with a man named Rick Wayne Valentini.
- Marlena Buffa remarks on Brian's behavior:
"He had a warrant for his arrest for driving on a suspended license for a traffic offense." (12:24)
Detectives soon discovered inconsistencies in Brian's identity, including mismatched Social Security numbers and birth dates. Further investigation uncovered that Brian Stewart was, in fact, Rick Wayne Valentini, who had forged a new identity to escape his troubled past.

"You have to be very careful because you only get one chance." (15:00)
Trial and Revelation

- Prosecutor Juan Martinez states:
"This is a really telling piece of evidence." (25:26)
During the trial, testimonies revealed Brian's deceit, including his false claims of a military background and fabricated personal history. A jailhouse informant provided crucial testimony, asserting that Brian had confessed to Jamie's murder.
- Andrea Aardsma, a witness, testified about Brian's negative remarks:
"Whiny, naggy bitch. Sugar mama. Nothing. Nothing positive at all." (32:29)

"I am the only human being who knows what happened. I'm the only human being who knows why things happened when they happened." (37:16)

- Jury Verdict:
"We, the jury...do find the defendant guilty." (41:24)

"Every time they mention her name, it hurts me so much. I think that I'm not going to see her anymore." (36:38)
