A condemned serial killer known as the “Grim Sleeper” who murdered nine women and a teenage girl in Los Angeles has died in prison, corrections officials said.

Lonnie D. Franklin Jr., who passed away Saturday at San Quentin State Prison after being sentenced to death in 2016, was linked to 14 slayings during his trial and detectives believe he may have killed as many as 25 victims throughout more than two decades.

Franklin was 67, California Department of Corrections and Rehabilitation officials said.

“Franklin was found unresponsive in his single cell on March 28 at about 7:20 p.m.,” prison officials said in a statement. “Medical assistance was rendered and an ambulance was summoned. Franklin was pronounced deceased at 7:43 a.m.”

Franklin’s cause of death is pending the results of an autopsy, but there were no signs of trauma, prison officials said.

Franklin — dubbed the “Grim Sleeper” due to an apparent 14-year hiatus in a string of killings that lasted from 1985 to 2007 — targeted women who abused drugs or worked as prostitutes during the crack cocaine epidemic. He often dumped their bodies on roadways or in the trash, but the slayings attracted little media attention, the Los Angeles Times reports.

Investigators ultimately linked the murders to Franklin — a city trash collector and former garage attendant for Los Angeles police — through ballistic and DNA evidence that identified a single suspect, the newspaper reports.

In 2010, a search of state offender records in California produced a partial match to Franklin’s son, leading police to collect a slice of pizza partially eaten by Franklin at a birthday party, which eventually tied him to the slayings, according to the Los Angeles Times.

Franklin’s attorney, meanwhile, criticized the decision by prosecutors to seek capital punishment against his former client, who was granted a reprieve last year along with 736 other condemned inmates when California Gov. Gavin Newsom halted executions in the state for as long as he holds office.

“As Lonnie Franklin’s attorney, I completely respect the jury’s determination that he was guilty of the most heinous crimes,” attorney Seymour Amster told the Los Angeles Times. “And to the victims’ families, I sincerely hope that the end of Franklin’s life bring some peace into theirs.”

Just 13 inmates have been executed in California since capital punishment was reinstated in 1978, most recently in 2006. As of Monday, 727 inmates are housed on the state’s death row, prison officials said.
