How did Henry McCarty, also known as William H. Bonney or Billy the Kid, die?

William H. Bonney was shot and killed by Pat Garrett in Fort Sumner on July 14, 1881. Bonney was an infamous Western outlaw who was called “Billy the Kid”. He was born in a poor Irish neighborhood on New York City's East Side. Before he was shot dead at age 21, Billy the Kid had reputedly killed 27 people in the American West. Billy the Kid called himself William H. Bonney, but his original name was probably Henry McCarty. Bonney was his mother Catherine’s maiden name, and William was the first name of his mother’s longtime companion–William Antrin–who acted as Billy’s father after his biological father disappeared.
