Samuel Little, who according to the FBI was the most prolific serial killer in US history, died in prison on Wednesday at the age of 80.
Little, who was eventually caught after being convicted of the deaths of three women in Los Angeles in the late 1980s, was serving three consecutive life sentences without parole, the California Department of Corrections and Rehabilitation said in its death notice.
An official cause of death is being determined by the Los Angeles County Medical Office.
Little was the subject of the Netflix documentary Catching A Serial Killer: Sam Little, who bowed on the streamer this year.
As a professional criminal, Little was not long imprisoned in his 40-year career, moving around the country. Finally in 2018 he confessed to killing 93 women nationwide from the 1970s to 2005. The FBI said he knew details that only the killer would know, and therefore his claims were considered credible.
Few may have murdered more than the alleged 93, and law enforcement officials across the country tried to link him to other unsolved cases. By last year they had confirmed at least 50 of his murder confessions.
Little was convicted of the murder of the three women killed in Los Angeles in the 1980s in 2014.
