The late great Jon Polito.
I hate to be lazy here, but I’m going to point to the respectful and comprehensive A/V Club obit. (Though couldn’t they have found something better for Detective Crosetti than the misguided “Homicide” movie?)
(And I need to see “Miller’s Crossing” again.)
Also among the dead: Jim Pruett, legendary Houston radio personality turned prominent (and often quoted in the media) gun store owner. Mike the Musicologist tells me he sold the store a while back; I’ve actually wanted to visit it, but the last few times I’ve been down to Houston it just hasn’t worked out for one reason or another.
