Murder Mysteries | "48 Hours" Full Episodes

David Temple spent nine years in prison for the murder of his pregnant wife, Belinda. His conviction was overturned because prosecutor Kelly Seagler withheld crucial evidence from the defense, including 1,319 pages of police reports focusing on an alternate suspect, Riley Joe Sanders. This misconduct led the Texas Court of Criminal Appeals to grant Temple a new trial.

David Temple stated, 'We're waiting for justice to be served once and for all and for the people that put me there and lied and cheated to be held accountable.' Defense attorneys highlighted that 1,400 pages of police reports were 'suppressed' and never seen by the original defense team. Investigator Steve Clappert found 'an extreme amount of interest' in Riley Joe Sanders in the reports, which were not fully disclosed.

Amy Gellard was brutally murdered during a home invasion in 1994, a case that remains unsolved over two decades later. Investigators struggled with a lack of clear motive, as the intruder stayed in the house despite opportunities to flee and showed little interest in valuables, leading them to believe Amy herself might have been the target. Primary suspects, Scott Manley and Dominic Kuka, both had drug problems, gave inconsistent statements, and failed polygraph tests, but no definitive physical evidence linked them to the crime.

The intruder used an unusual dagger and a prop gun, wore a black ski mask and gloves, and spoke with a Mid-Atlantic accent. Bunny Leighton described the intruder as 'pacing' and 'waiting for a ride.' Scott Manley, a friend of Amy's and a cocaine addict, lied about his whereabouts and owed Amy money. Dominic Kuka, from Pennsylvania, placed himself at the crime scene but denied involvement, and his alibi did not check out.

Carolyn Ael was murdered in Seoul, South Korea, in 1988. Her friend and fellow teacher, Kathy Patrick, became the prime suspect after another friend, Sandra Ames, confessed to helping stage the crime scene and implicated Patrick, suggesting unrequited romantic feelings as a motive. Despite a South Korean arrest warrant, Patrick could not be extradited to the US due to the lack of a treaty, and crucial physical evidence was later destroyed, preventing prosecution. This case ultimately spurred the passage of a US law in 1994 allowing federal prosecution of Americans who murder other Americans abroad.

Sandra Ames stated Kathy Patrick came to her saying, 'I think I killed Carolyn.' Ames later pleaded guilty to harboring a criminal and suppressing evidence. Investigator John Boatright believed Kathy Patrick was the killer, stating, 'Kathy really fell for Carolyn.' Kathy Patrick denied involvement and failed a polygraph test. Wanda Ael, Carolyn's sister, confirmed her family's lobbying efforts led to the 1994 law.
