Lunicidal(2008)

John Good is a kinder, gentler serial killer with a heart of gold. "Lunicidal" follows his exploits as he learns he has to contend with a new kid on the block - a slashing demon from Hell. This new nuisance from the pits of Hades has no concern for the community and is a bit of a litterbug as he drops evidence such as slaughtered teen body parts all over town; something John Good would never do. John Good seeks to right these wrongs and go to war against this untidy culprit.
