Carlin Cornett

69-year-old Carlin Edward Cornett was arrested on September 14, 2021 for the July 31, 1974 robbery and murder of 22-year-old Christy Bryant in National City, California. Bryant was working alone as a clerk in a 7-Eleven store when she was stabbed to death by an unknown person during a robbery. Bryant was working in National City at the time, after being recently discharged from the Marines.

A DNA profile of the suspect was developed from blood recovered the scene. The profile was entered into CODIS in 2008 but produced no hits.

The FGG investigation was conducted by the San Diego County District Attorney’s Office using an in-house genealogist working as part of the Cold Homicide and Research Genealogy Effort (CHARGE).

Cornett was detained at his home in Las Vegas. On October 25, 2021, Cornett was arraigned in San Diego County Court, where he pled not guilty to a charge of murder.
