Sheriff, Coroner Resume Digging In Glendora Yard In 1978 Cold Case Disappearance

GLENDORA (CBSLA.com) — Los Angeles County Sheriff's detectives and the Coroner's Special Operations Team Thursday resumed digging in the backyard of a Glendora home in connection with a 35-year-old cold case disappearance.

Authorities began searching the yard of a home in the 500 block of Essex Street Wednesday for any evidence related to the disappearance of 24-year-old Wendy Byron.

Byron was living at the residence with her husband at the time her family reported her missing in August 1978. Her car was later found at Ontario International Airport.

"We received information that led us to this house," Lt. Holly Francisco said. "We're not gonna say what information as to not jeopardize the investigation," Lt. Holly Francisco said.

Byron's disappearance was called suspicious at the time, yet no suspects or her body ever surfaced.

The Glendora Police Department, which conducted the original investigation, recently handed the case over to the LASD after exhausting all leads.

Authorities returned to the home Thursday around 7 a.m. with shovels, buckets and ground-penetrating radar to look for clues. The Coroner's office later left the scene around 10:30 a.m.

"This type of search was not available 35 years ago, so we're starting from scratch," Lt. Fransisco said.

Byron's disappearance  is being treated as  a missing persons case until new evidence proves otherwise, officials said.

The home's present owners are not involved in the case.

Detectives have no immediate plans to question Byron's husband.
