Man in Much-Viewed Web Video Is Arrested in a New Jersey Killing A hitchhiker who became an Internet sensation early this year when he used a hatchet to hit a man who had struck a utility worker with his car was arrested on Thursday night, on charges that he killed a man in his home near Elizabeth, N.J., on Sunday, the authorities said. The man, Caleb Lawrence McGillvary, 24, who was taken into custody at a Philadelphia bus station, is accused of killing Joseph Galfy Jr., 73, at his home in the town of Clark on Sunday, said Theodore J. Romankow, the Union County prosecutor. Mr. Galfy died of "blunt force trauma" and was found unresponsive in his home on Monday, Mr. Romankow said. The circumstances of Mr. Galfy's death, and Mr. McGillvary's precise involvement, were not immediately clear. But Mr. McGillvary suggested on his Facebook page on Tuesday that he might have been subjected to a sexual assault and that he might seek retribution. Mr. McGillvary, who, according to Mr. Romankow, roamed the United States relying "on the generosity of strangers for food, lodging and transportation," became known on the Internet as "Kai the Hatchet-Wielding Hitchhiker" after the episode in which he struck the man who had hit a utility worker in Fresno, Calif., with his car. An interview with Mr. McGillvary on local television after that has been viewed nearly four million times, and he appeared on ABC's "Jimmy Kimmel Live" in February. Mr. McGillvary's bail was set at $3 million on Thursday, and he was being held in the Union County Jail in Elizabeth, N.J., Mr. Romankow said.
