Samuel Little, a man described by the FBI as the most prolific serial killer in US history, has died aged 80.
Little died in a California Hospital.
He was serving a life sentence for the murder of three women. But by the time of his death, he had confessed to killing 93 women between 1970 and 2005.
Officials say Little targeted vulnerable individuals, many of whom were sex workers or drug users.
Last year, the FBI said its analysts believed all of his confessions were "credible".
Little was arrested in 2012 on a drugs charge in Kentucky and extradited to California, where officers carried out DNA testing on him.
He already had an extensive criminal record, with offences from armed robbery to rape across the US.
The DNA results linked him to three unsolved murders from 1987 and 1989 in Los Angeles County. He pleaded not guilty at trial, but was eventually convicted and sentenced to three consecutive life sentences, with no chance of parole.
