Bendik -- a 35-year-old club owner -- was in Philadelphia on a business trip and was seen out and about Wednesday night with Tobin and friends, TMZ reports. Bendik's body was allegedly found by a hotel maid the following day.
The Philadelphia County medical examiner's office has not yet confirmed that it was Bendik's body that was found and there is no word on where Tobin might have been at the time.
Sources say that while Bendick ran several major clubs nationwide -- including LA's DBA Nightclub and AV Nightclub -- he was not much of a partier himself. His friends are family are allegedly "shocked and devastated" by news of his death.
Tobin has played mean-girl Kitty Wilde since the fourth season premiere of the Fox musical comedy.
