Luke, a hitman for mafia boss Sam Giancana, looked up at the School Book Depository building knowing Lee Harvey Oswald was inside waiting.
He was told Oswald was going to try and assassinate President J.F. Kennedy as his motorcade slowly drove by in downtown Dallas. They told him Oswald was going to be the false sponsor for the murder.
Luke checked under his trench coat, touching the Mannlicher-Carcano rifle briefly. Identical to the one Oswald had. No one noticed him blend into the tree line of the grassy knoll.
He waited until the time was right, took aim and fired!
