‘Grim Sleeper’ killer Lonnie Franklin, 67, dies in California prison after four years on death row

Lonnie Franklin, the convicted serial killer known as the ‘Grim Sleeper’ who preyed on the women of South Los Angeles for more than two decades, has died in prison. He was 67.

California corrections officials said Franklin was found unresponsive in his cell at San Quentin State Prison on Saturday at 7.20pm. Medics tried to revive him but he was pronounced dead at 7.43pm.

‘There were no signs of trauma,’ California Department of Corrections and Rehabilitation spokeswoman Terry Thornton told People on Sunday. ‘They don’t know why he died.’ 

An autopsy will determine the cause of death; however, there were no signs of trauma, corrections spokeswoman Terry Thornton said in a statement.

Franklin had been on death row since August 2016 for the deaths of nine women and a teenage girl; Debra Jackson, Henrietta Wright, Mary Lowe, Bernita Sparks, Barbara Ware, Lachrica Jefferson, Monique Alexander, Princess Berthomieux, Valerie McCorvey and Janecia Peters.

Berthomieux, 15, was a runaway strangled in Inglewood, California. 

Franklin was linked at trial to 14 slayings, including four women he wasn’t charged with killing. Police have said he may have had as many as 25 victims since 1984.

Most of the victims were fatally shot at close range with a .25 caliber pistol, though two were strangled. Their bodies were dumped and left to rot in alleys and trash bins.

Franklin was also convicted of the attempted murder of Enietra Washington. She testified that Franklin shot her, sexually assaulted her and took a Polaroid picture of her before pushing her out of his vehicle and leaving her for dead 27 years ago. 

Singer-and-actress Macy Gray portrayed Washington in 2014 documentary The Grim Sleeper.

The murders went unsolved for years and Franklin avoided suspicion by working as a city trash collector and onetime garage attendant for Los Angeles police.

The killer earned his moniker because of the apparent hiatus from the late 1980s to 2002. But his final victim was Peters, 25, in 2007. 

Community members complained that police didn’t seriously investigate the killings because the victims were black and poor and many were drug users and prostitutes during the crack cocaine epidemic.

Franklin was connected to the crimes after a task force that re-examined the old cases discovered that DNA from Franklin’s 28-year-old son, which was in a database because of a 2009 weapons possession arrest. It showed similarities to genetic evidence found on some of the ‘Grim Sleeper’ victims. 

A detective posing as a busboy at a pizza parlor collected utensils and crusts while Franklin was attending a birthday party. Lab results connected him to some of the bodies from deaths in 2002, 2003 and 2007 and led to his arrest.

Last year, Franklin was granted a reprieve when Gov. Gavin Newsom halted the execution of more than 700 condemned inmates on the nation’s largest death row for at least as long as he’s governor.

California hasn’t executed anyone since 2006, under then-Gov. Arnold Schwarzenegger, and inmates are far more likely to die of old age.

The stepmother of a victim named Barbara Ware told People magazine she was shocked by the news.

‘I won’t say I’m pleased he died but at the end there was justice for all the bad things he did in his life,’ Diana Ware said. ‘We can now be at peace.’
