Henry Spivey is a hired thug working for ruthless contract assassin Marcos Siazon.
Much of Spivey's past is unknown but his rap sheet reveals that on August 6th, 1996 in Bethseda, Maryland, Spivey was arrested for the murder and attempted rape of a Navy Lieutenant.
Spivey was tried for first degree murder but due to circumstantial evidence against him, he was offered a plea bargain of manslaughter instead which led to Spivey serving an eight year sentence for it.
Spivey later escaped from prison on December 2nd, 2002 and as such, a murder warrant was issued for him.
Presumably, at some point, after his escape, Spivey met Siazon and joined Siazon, becoming one of Siazon's hired thugs.
