This episode covers the unsolved case of a man who committed multiple crimes in California in the 1950s, including the murder of two police officers. It discusses advances in forensic technology that eventually led to the identification of the suspect, Gerald Mason.
The episode recounts the events of May 22, 1957, when Bob Door and his date were attacked by a gunman in El Segundo, California. The assailant robbed the couples, sexually assaulted one of the girls, and later shot two police officers who stopped the stolen vehicle.
Investigators struggled for decades to identify the suspect, initially focusing on fingerprints and leads that went cold. A breakthrough occurred in 2002 when a woman claimed her uncle had bragged about the murders, prompting a fresh investigation.
Using modern fingerprint analysis, investigators matched a thumbprint from the crime scene to Gerald Mason, who had been living a quiet life in South Carolina. Further handwriting analysis linked him to an alias used when purchasing the murder weapon.
Mason was arrested and ultimately confessed to the murders, receiving two life sentences. The episode highlights the role of technology in solving cold cases and the complexities of criminal behavior.
A 1950s California murder case is solved decades later through advanced fingerprint and handwriting analysis, identifying Gerald Mason as the killer.
