William Johnson "Petite" Clayborn, played by John Eddins, was contracted by Junior's crew to kill Tony Soprano via intermediary Donnie Paduana. First attempt was aborted when Christopher inadvertently boxed in the car the would-be assassins were using. Clayborn attempted to get Christopher to move pretending to be a police officer, but to no avail. The second attempt also failed and Clayborn was accidentally shot and killed by his partner Rasheen Ray.
