Maniac Cop

Matthew "Matt" Cordell was a well-known and respected police officer, but had little regard for the rules of the force. He was thrown into Sing Sing prison for "violation of people's rights", but Cordell believed (correctly) that his superiors were framing him. Cordell was sentenced to several years in Sing Sing by a judge and arrives in the prison where he is recognized by all of the inmates that he arrested and put there. In the showers, Cordell is attacked by three knife-wielding inmates. Cordell puts up a fight and beats up the three men until one of them stabs him in the back. He falls and the rest of the men stab and slash him in the face over and over again.

On the day that Cordell was attacked in the showers, doctor Gruber discovered that he was still alive, and revived the near-death officer. Despite being stabbed multiple times, Cordell was technically brain dead, yet he continued to live. Sympathetic to Cordell's plight and aware that Cordell was framed by his own superiors, Gruber declared Cordell legally dead and did not see any harm in making people think he was still alive (which he was technically not).

After 10 years, Cordell, now known as the Maniac Cop, starts a killing spree, but is defeated. He comes back for a second time but ends up defeated again, but this time he is buried with full honors. Two years later, a priest practicing the Voodoo arts resurrects the Maniac Cop to do his bidding.
