One of Costanza’s bosses plays on The Bridge. I recognized his voice immediately. The one where George inserted his pic into a framed photo.

The main boss in pic substitution episode -- hilarious BTW -- just died last year. A very sad story. He had lost most of one leg to diabetes and they were going to take bits off the other one. He tried to commit suicide, but pulled the shot back. Too late; he had time to call 911, but died several days later.

Is this who you're thinking of? http://www.cbsnews.com/8301-31749_162-57383830-10391698/seinfeld-actor-shoots-self-in-apparent-suicide-attempt/
