William James "Willie" Bosket, Jr. (born December 9, 1962) is an American convicted murderer, whose numerous crimes committed while he was still a minor led to a change in New York state law, so that juveniles as young as 13 could be tried as an adult for murder and would face the same penalties. He has been in either prison or reformatories for all but 18 months since 1971, and has spent all but 100 days of his adult life in custody. He is currently serving a sentence of 82 years to life at Five Points Correctional Facility.
Bosket was born in Harlem. His father, Willie Sr. (Butch), killed two people in a Milwaukee pawn shop shortly after his son was conceived and was sentenced to life in prison. His mother, Laura, had nothing to do with him, leaving Bosket to fend for himself. Early on, he gained a reputation as a violent child—a reputation on which he prided himself; he told juvenile authorities that one day he would be a killer just like his father. He was in and out of various reformatories from age nine onward. However, at the time the prevailing view was that a juvenile was incapable of committing a crime, so he always ended up back home. Nonetheless, it was believed early on that he would make good on his prediction that he would kill someone.
On March 19, 1978, Bosket, then fifteen years old, shot and killed Noel Perez on a train operating on the 3 New York City Subway service during an attempted robbery near the Harlem – 148th Street terminal station. Eight days later, Bosket and another accomplice shot dead another man, Moises Perez (no relation to his first victim) in another attempted robbery at the back of another 3 train at the 145th Street station, one station south of 148th Street (cornering the victim at the back of a train, as the subway station is one of just two in the system that can only board the first half of a subway train). In between, Bosket and his accomplice shot a New York City Transit employee working in the Lenox Terminal yard adjacent to the Harlem – 148th Street station and committed two other armed robberies, one of them on the A service.
