Somebody probably posted this before but I have no time to go through the whole thread. I found a Stephen Murphy, in a 1992/93 Navy register, that I feel has a lot of resemblance:

Since you apparently won't allow an answer to your unkind private message that called this post "ridiculous", I thought I'd explain my line of reasoning here; where both the persons looking for Steve and you can review it.
It could be that I skipped over it but: The missing Stephen Lee Murphy, from what I skimmed through, had no military MC record after 1976, when he disappeared.
While I admit it isn't the most likely case, I wanted to leave the judgement of this information up to those searching for him. Personally, I see a lot of resemblance in the picture, especially the nose, but I could be completely wrong.
Him quitting/abandoning the MC in 1976 and then (re)joining another military branch a few years later is not out of the realm of possibility. In the 70's/early 80's there weren't wide-spread centralized databases like there are now and a popular name like Steve/Stephen Murphy won't necessarily ring alarm bells.
I have no idea which awards he has on his uniform and am more than happy to admit it is impossible that it is him, if these couldn't be gathered in, let's say, a period between 1980-1992.
In any way, you coming at me like that is completely un-necessary. Websleuths is a kind community and it would be great if we could keep it this way.
