You remember "Kai," the homeless hitchhiker who used a hatchet to stop an attacker?
Well, he's now accused of killing a 73-year-old attorney in New Jersey.
He was arrested last night at a Philly bus station after a massive manhunt.
A prosecutor says a Facebook post indicates the two had some kind of relationship.
Kai's real name is Caleb Lawrence McGillivray.
Investigators say he cut his hair after police started looking for him.
They also say he left a mysterious Facebook message about possibly being drugged and assaulted.
