The actor, Jerry Orbach, supposedly saw who done it but refused to tell police out of some misguided loyalty to mobbed up friends.
I can't understand how he didn't get arrested for withholding testimony.
First, I think you're thinking of when Joe Gallo got killed. Second, he wasn't arrested because "withholding testimony" isn't a crime.. Perjury is a crime, but you'd have to be on the stand first.
