Smash! Smash! Sah-MASH!

The words made Kai the hitchhiker an instant Internet star in his heroic efforts to save a homicidal man from killing innocent people, but now he's wanted for murder himself.

Authorities in Union County, N.J., said in a news release they're looking for Kai, whose real name is Caleb McGillvary, in relation to the homicide of Joseph Galfy, a lawyer who was found dead in his New Jersey home on Monday.

In a press conference this morning, Union County prosecutor Theodore Romankow said they believe Kai shaved off his famous dreadlocks in an attempt to conceal his identity and is considered armed and dangerous.

An autopsy determined the 37-year-old Galfy died of blunt force trauma, the prosecutor's office said.

In a graphic Facebook post the day after the alleged crime, Kai insinuated he had been sexually assaulted.

"what would you do if you woke up with a groggy head, metallic taste in your mouth, in a strangers house... walked to the mirror and seen come dripping from the side of your face from your mouth, and started wretching, realizing that someone had drugged, raped, and blown their fuckin load in you? what would you do?"

Kai is well known on the Internet for his interview with a Fresno TV station talking about a bizarre incident involving a driver who allegedly ran down a utility worker and turned on female bystanders before Kai intervened.

"A guy that big can snap a woman's neck like a pencil stick," he told the reporter "So I f--king ran up behind him with a hatchet. Smash, smash, Sah-MASH!"
