Samuel Little, 79, jailed since 2014, has admitted that between 1970 and 2005, a total of 93 people, mostly women, have been killed in police-proven crimes, 50 of them so far, making him the worst serial killer in history, US authorities said yesterday. America, according to "Sky News."

Since 2014, Little has been serving a life sentence after being convicted of three murders, but the number of victims appears to be much higher, the FBI said.

"For many years, Samuel Little thought he could not be arrested because no one cared about his victims," ​​said FBI criminal analyst Christie Palazzolo.

"Although he is already in prison, the FBI considers it important to bring justice to all his victims."

According to the FBI, his investigators believe that all the crimes Little confessed to commit are probably true, and for this reason the FBI has created a website that posted the serialized confessions of the serial killer, which tells the murders he has committed, and whose victims have yet to be identified.

"Many of these deaths were originally categorized as overdose, accidental deaths, or without a specific cause. Some of the bodies have not been found," the FBI said on the website.

Little Boxer, also known as Samuel McDowell, was first arrested in 2012 at a homeless shelter in Kentucky, which turned him over to California as part of a drug investigation.
