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-Ledger has 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.
Kai will be processed in Philadelphia and sent to back to New Jersey in the following week. His bail is set at $3 million.
