The photo is thought to have been taken between the late 1970s and the early 1980s, Newport Beach police said.
Neal, 72, was arrested Tuesday by authorities in Colorado, where he lives and remains in custody. Barring any legal challenges, he awaits extradition to California, according to Newport Beach police.
Neal has been charged with special-circumstances murder, kidnapping and lewd and lascivious acts on a minor under 14 in connection with Linda’s death.
Authorities say Neal went by the name James Albert Layton Jr. at the time of the killing. Investigators believe that he lived in Southern California in the 1970s and changed his name following an incident in Florida.
A sketch of a person of interest in Linda’s death was circulated at the time of the killing, but it generated no leads.
DNA testing wasn’t available at the time. Instead, investigators tested bodily fluids and blood left at crime scenes for proteins that helped provide clues or narrow a list of suspects.
The science eventually became key to the case.
Newport Beach detectives in 2018 contacted Parabon NanoLabs, a Virginia-based medical lab, which used DNA from the crime scene to calculate a possible suspect’s facial composite, gender, ancestry, freckles and skin tone, and eye and hair color.
