Donald Leroy Evans was arrested in Mississippi in 1991 for kidnapping a ten year old girl. He confessed to killing her, and then claimed to have killed more than 60 other people across 20 states, starting in 1977.
The police were skeptical of his claims about the rapes and murders in public parks and rest stops, but he gave some descriptions that perfectly matched unsolved cases in Florida and Illinois.
Evans briefly escaped from Harrison County Jail in Mississippi, but he was quickly recaptured.
In 1993, Evans was tried and convicted in Mississippi of the kidnapping, rape, and murder of 10 year old Beatrice Routh. He was sentenced to death. In 1995, he was tried and convicted in Florida for the 1985 murder of Ira Jean Smith, a 38 year old woman.
Evans was never executed because a fellow death-row inmate fatally stabbed him in 1999.
Some people speculate that his confession of killing over 60 people is part of an elaborate scam, but he was confirmed to have killed 3 people.
