Rodney Alcala Update: Six Cases Possibly Linked to Serial Killer's Stash of Photos

SANTA ANA, Calif. (CBS/AP) Investigators from Washington State to Arizona are looking at cases from before 1979 to determine if any of them can be connected to Rodney Alcala, the convicted California serial killer whose stash of photographs may be a disturbing portfolio of victims.

Last week, Huntington Beach police released more than 100 old photos mainly of unidentified young women, girls and even babies. They believe Alcala took the pictures in the 1970s and placed them in a storage locker he rented before his arrest in 1979, for the rape and murder of 12-year-old Robin Samsoe.

Orange County District Attorney Tony Rackauckas said Thursday that his department was looking at about six other cases they believe could be connected to Acala.

"What we'd like to do is to try to identify anybody who might be another one of his victims and try to help these people," Rackauckas said. "Find some sort of knowledge as to what it was that happened to their missing loved ones."

Some of the calls to the Huntington Beach Police Department came from relatives and friends of at least four women who disappeared or were killed in the '70s. Police are working to confirm any possible connection to the pictures and establish a timeline of Alcala's whereabouts during that decade

Even before the photos were released, New York City police were investigating Alcala in three other cases, while law enforcement agencies in New England were taking a look at five other cases, authorities have said.

A jury earlier this month recommended the death penalty for Alcala in the serial slayings of Robin Samsoe and four other Los Angeles County women between 1977 and 1979.

Witnesses testified that Alcala was seen snapping pictures of Robin Samsoe and her young friend on the beach just minutes before she disappeared. He was tied to the other four murders through forensic evidence, including DNA.

Anyone with information about the women in the pictures is asked to call Huntington Beach Police Detective Patrick Ellis at 714-375-5066.
