There wasn't a picture, or I could answer with more assurance, but the age sounds about right.

He used to be a Minicon regular and IIRC an occasional Minn-stf meeting attendee, but I remember him best from an incident at a con where Geri Sullivan noticed that he had a gun tucked into the back of his pants. (This was years before the concealed carry law was changed.) The memory is hazy, but I believe Geri persuaded him to take the gun elsewhere.

Very sad, if so.
