Lonnie Franklin Jr., also known as the Grim Sleeper, was a serial killer who terrorized Los Angeles for decades, targeting primarily Black women, often involved in prostitution or drug addiction. He was convicted in 2016 for the deaths of 10 women and a teenage girl, and the evidence suggested he may have been responsible for many more murders. Franklin's crimes went unpunished for years due to police indifference and the assumption that his victims were vulnerable and often overlooked by authorities. While Franklin was convicted and sentenced to death, he died in prison before his sentence could be carried out. Despite his death, investigations are ongoing, and authorities believe there may be many more victims yet to be identified.
