Once again, with all due respect, I'm confident that whatever medals he did receive he did not receive the Medal of Honor.
This page shows what medals he did receive:http://www.virtualwall.org/dg/GarnerRL01a.htm
You may be able to get his military record so take a look at this page.http://www.homeofheroes.com/valor/replacement_medals.html
With the additional information provided and a better search on my part I did find him on the WALL. http://thewall-usa.com/info.asp?recid=17940
If you have a picture you could honor his memory by adding it here.
Best of luck to you.
