Billy the Kid by 9JD Pin

He arrived in Lincoln County in the state of New Mexico where he lived for only four years, beginning as a cowboy and ending up being one of the most famous gunmen in the territory. He was held responsible for the death of twenty-one men, although only nine of them have been tested, of which five occurred in shootings in which other men intervened alongside him (so it is not known whether he was the author or not of said deaths), two in self-defense, and another two during one of their jail leaks.
