As far as I know my parents have no pictures of him at all. He had real short hair and was graying on the sides and top quite a bit. He did have a face that kind of revealed his Irish descent. I seem to remember his face was somewhat red in the few times I saw him in 74-75. I think that must have come from his excessive drinking. I also can not remember the car he was driving. But from my memory. I want to say he used to drive an early 70's Chevrolet. He always wore darker color (blue,gray,brown) suits. I always remember whenever I saw him he used to have his dress shirt and tie a bit loose so that it showed a white t-shirt underneath. But that was when he was sitting down and talking.
I did also find out that Casey grew up in DC and in the 1940's attended Gonzaga and also Coolidge High Schools. I also found out that he graduated from Duquense University in Pittsburgh Pa. I do also know his oldest son is an eye doctor in Raleigh NC. Though I do not think there was ever much communication between Casey and his kids after the 1970's. Before his divorce, he and his family had lived in Potomac in the the early 70's on a street I believe is called Goya Drive.
My dad did a follow up with the police in the 1970's. From what the police told my dad is that they thoroughly checked Casey out and could not hold him because they were unable to find any evidence to link him.
Though the tape recorder was a quite popular gadget during that period. I still think it odd that he used to carry one around in his briefcase.
I did call the Montgomery County Police in Feb and spoke to a detective. He said he would pass on the info to the detectives in charge. I also told him I was posting info here on websleuths. Maybe if Casey is still alive they will go and re-interview him and if he was in fact involved he will now tell them.
If this helps to anyone who may remember seeing TRM. If it was Bob Casey. I seem to remember him having blue eyes and very short hair that was mainly turning gray. Of the two sketches released by the Montgomery County Police. The one of the right looks somewhat similar to Casey.
