Murphy and Jenkins

Murphy and Jenkins were two corrupt South Park police detectives. When Stan, Kyle, Kenny and Cartman joined the force as junior detectives, the pair immediately suspected that the kids knew they were on the take from drug boss Gino, and were openly antagonistic towards them. During a raid against the Peppermint Hippo, the two revealed their true colors when Jenkins shot Hopkins. Murphy then shot Gino and Jenkins as well so nobody would know of his corruption. Then, reasoning he couldn't even trust himself, Murphy committed suicide.
