A neck tattoo on Caleb McGillvary, also known as Kai, was what helped a New Jersey resident lead police to the animated hitchhiker wanted in connection with a slaying, New Jersey prosecutors said Friday.

McGillvary, 24, the hatchet-wielding hitchhiker of “Smash, smash, suh-mash!” fame, was arrested in Philadelphia on Thursday night at a Greyhound Bus stop.

Authorities in Union County, New Jersey, named the couch-crashing drifter as a suspect in the death of New Jersey attorney Joseph Galfy.

Prosecutors said a resident in Cherry Hill saw McGillvary’s photo during a broadcast news story about Galfy’s slaying and recognized him from hours earlier. The resident had seen McGillvary with a neighbor who ended up taking the famed hitchhiker to the train station, prosecutors said.

Once the neighbor found out McGillvary was wanted in connection with a killing, they called police.
