Kai was arrested Friday in a Greyhound Bus station in Philadelphia and charged with the murder of Joseph Galfy Jr.
Authorities believe that Kai and Galfy spent a night together romantically at Galfy's home in New Jersey before things became violent.
The New Jersey Star-Ledgerhas an account of how Kai met 73-year-old Joseph Galfy Jr. and how their sexual relationship ended in Galfy's death.
They met, an unlikely pair, in Times Square last Saturday night.
One, a 73-year-old partner in a Rahway law firm and member of his hometown's Chamber of Commerce, the other a 24-year-old itinerant with long hair and a penchant for upturning convention that had landed him a minor internet presence.
Their rendezvous, most of it later spent in and around Joseph Galfy Jr.'s ranch-style house on Starlite Drive in Clark, would last about 24 hours, until sometime Sunday evening when, authorities said, their encounter turned violent after a sexual tryst.
Kai, however, claims it was not a consensual sexual relationship, posting this on his Facebook page the day after Galfy's body was found by authorities.
