UPDATE: Deputies Continue to Search for Missing Woman's Remains

Update 1 p.m.
Los Angeles County Sheriffs Homicide detectives are disclosing very little information in their reopened investigation into the 1978 disappearance of Wendy Byron, a 24-year-old Glendora woman.

Homicide detective Lt. Holly Francisco told media Thursday that investigators are literally starting the investigation from scratch, using sophisticated technology, including sonar equipment to scour the backyard of Byron's former residence in the 500 block of Essex St.

Francisco said that Glendora Police recently reopened the case hoping that new technology would generate a lead into the case that went cold 35 years ago.

Francisco said other information led investigators to search the backyard, but would not disclose what that information was.

No new evidence has been uncovered in the backyard, Francisco said. She said sonar equipment did detect an "anomaly," but nothing to provide a lead in the case.

Although much focus was placed on Byron's husband Robert during the initial investigation 35 years ago, Francisco said no person is being identified as a person of interest in the reopened case.
Glendora Patch approached Robert Byron's current residence in Covina Thursday afternoon, but he declined to comment.

Francisco also dispelled rumors that evidence of foul play was discovered in the backyard when the home's current owners began digging the backyard to build a swimming pool.

Wendy Byron was never declared dead following her disappearance, according to Francisco. 

Updated 11:23 a.m.

Sheriffs deputies, Glendora Police and homicide detectives are continuing to excavate the backyard of a Glendora home searching for the remains of a woman missing since 1978.

Authorities began the search for Wendy Byron, a 24-year-old woman who went missing 35 years ago, in the backyard of a home in the 500 block of Essex Street Wednesday. 

The home was the former residence of Byron and her then husband Robert, who has since moved from the property.  Byron's car was found abandoned at Ontario Airport and authorities then suspected foul play, with suspicions focusing on her husband. But with no other clues to work with, the case went cold. Robert Byron, who was never charged in the disappearance of his wife, is currently not speaking to the media. Media reports list his current residence in Covina.

But authorities reopened the case and began searching the Byrons' former residence Wednesday. Holes were dug up throughout the yard and a cadaver dog sniffed the area Thursday morning. However, the dog did not pick up a scent. 

Authorities began using sonar equipment and did pick up an anomaly. There is still no word yet on whether Byron's remains or any other evidence in this case has been discovered.

The current property owners of the house are not involved in this case, according to authorities.
