Kai the hitchhiker, who captivated the Internet in February with an act of heroism and a contagiously entertaining local TV interview, is now a murder suspect in New Jersey.

Union County law enforcement has issued an arrest warrant for him for the murder of Joseph Galfy, Jr., in Clark, N.J., according to the Union County Prosecutor's Office.

Galfy was reportedly found dead inside his home on May 13. The cause of death has been declared as blunt force trauma. Authorities say Kai — identified by his full name, Caleb Lawrence McGillvary — is considered armed and dangerous and has cut his hair in an effort to conceal his identity. He's charged with murder and bail is set at $3 million.

McGillvary, a.k.a. Kai, was passing through Fresno, Calif., in February when he saw a man attack a utility worker with a car and assault a woman at a gas station. He then hit the man on the back of the head three times with a hatchet to stop the attack, and his interview shortly thereafter became a viral sensation. Videos of him have since been viewed millions of times on YouTube and he appeared on Jimmy Kimmel Live, where Kimmel gave him a surfboard as a present.

So what could have prompted such a dark turn in McGillvary's story? While his official take is unknown, below is a cryptic status update to his Facebook page from Tuesday, the day after Galfy was found dead.

Be warned; it contains graphic, NSFW language.

Police say McGillvary was last seen at a light rail station near Haddonfield, N.J., and are offering a $5,000 reward in the case.
