Actor Daniel von Bargen, who played George Costanza's boss Mr. Kruger on Seinfeld
, was hospitalized this week after a failed suicide attempt in Ohio.
Von Bargen, 61, shot himself in the temple in his Cincinnati apartment on Monday morning and then called the police, according to TMZ.com
, which obtained audio of his 911 call.
"I've shot myself in the head … and I need help," he tells the operator.
The actor, who is diabetic, says he was distraught because he was scheduled to go to hospital to have "at least a few toes" amputated.
Von Bargen was said to be in critical condition at an Ohio hospital.
