"Remembrance of Things Past" is a common English title for "À la recherche du temps perdu," a novel in seven volumes by Marcel Proust, written between 1909 and 1922. A more literal translation is "In Search of Lost Time."
The Grim Sleeper was a name given to real-life serial killer Lonnie David Franklin Jr. who operated in Los Angeles from 1985 to 1988 and again from 2002 to 2010, which led to his title being given to him by the press because his killing spree stopped for 14 years. He first started killing shortly after his release from military prison in 1985; he had been serving a 10 year sentence for raping a 16-year-old girl in Germany while he was stationed there in the U.S. Army. Shortly after, he started raping and killing prostitutes and drug users, but at the time the L.A.P.D. had little interest in investigating the murders; it wasn't until the community pressured them that they began investigating. Franklin killed his victims by shooting them; he preferred to use a .25 Auto, but he went undiscovered due to a forensics mistake matching the bullets to a Deputy Sheriff's backup weapon. Franklin's victims weren't linked until May of 2007 when D.N.A. testing on a victim matched D.N.A. from eleven other unsolved murders. Franklin was eventually identified and arrested in July 2010; he was tried and convicted of 10 counts of murder in the first degree and one count of attempted murder in the first degree. The jury also requested the death penalty for Franklin. On May 5, 2016 a California Supreme Court judge officially sentenced Franklin to death. On March 28, 2020 he was found dead in his cell. The cause of death has not been released (as of 2021).
