Police are turning to social media to help identify 42 women whose photographs were found in possession of a suspected serial killer known as the Grim Sleeper.
"If anyone recognizes any of the women in the photographs, Facebook or Twitter may be used to make a positive identification," according to the Los Angeles Police Department.
The featured photographs were among the hundreds seized from the home of Lonnie David Franklin Jr., a South LA man arrested in 2010 on suspicion of killing at least 10 young women between 1985 and 2007.
Many of the victims were prostitutes, whose remains were found in alleys and trash bins around South Los Angeles, authorities said.
The "Grim Sleeper" nickname is attributed to an apparent 14-year hiatus between alleged killings.
Police credit ballistic and DNA evidence for a break in the investigation, which spanned more than 20 years. Prosecutors are seeking the death penalty against the former city sanitation worker.
