Authorities investigating a suspected serial killer said they got at least one promising lead after releasing photos he took of nearly 50 girls and women.

A young woman in the pictures strongly resembles a woman who disappeared in 1983 from a Florida bar, they said.

The lead came as authorities look into whether William Richard Bradford, who is on death row for murdering two aspiring models in the 1980s, is responsible for other rapes and killings from 1975 to 1984.

The 54 photos, showing 47 women, were seized from Bradford's home in 1984 but sat untouched for years. Los Angeles County sheriff's detectives posted them last month in hopes that the public could help account for the women.

So far, only 23 have been positively identified as alive, said Sheriff's Capt. Ray Peavy.

Among the women who came forward was Eva La Rue, an actress on the CBS drama "CSI: Miami," who said Bradford photographed her and her sister, Nika, two decades ago.

The family of Darlene Ann Webb — who disappeared in January 1983 after leaving a bar in Daytona Beach, Fla. — told sheriff's officials she looks like a woman who is in one of the photos.

Authorities said Bradford, now 60, took pictures of women he met at bars and elsewhere under the promise of helping their modeling careers.

Bradford was living in Los Angeles at the time but had resided in Florida at some point, officials said.

Bradford has denied killing anyone and is appealing his conviction and death sentence. His attorneys contend that although he had the photos, he may not have taken them.
