Although I can't recall ever seeing any pictures of him naked (or even without benefit of trousers or shirt), I will not give up hope that they may exist.
Mahoney is scheduled to turn 68 this June. Born in England the 7th of 8 children, he came to the U.S. and joined the Army in order to secure American Citizenship.
Through various searches, I was able to find that a one point along the way he was married-although her name is not listed, it only states 'married briefly'.
