Looking for Army buddy information

I need your help and I am looking for some information. My name is Dale Lalim and we live in Maynard, Minnesota. I was in the Army and stationed in Viet Nam from 1970 - 1971 with a buddy of mine from International Falls area. I was Spec 4 with the 45 Engineering Battlion. We spent many good hours together during this tour. He was on his second tour and was married as was I. Unfortunately I cannot remember his name and he died in action and I want to pay my respects to him as we visit the Wall in Washington this Fall. I also have many pictures I would like to share with his family so I hope some one in your area can help me out. If you know of this Veteran can you please write me at Dale Lalim, PO Box 73 Maynard, Minnesota 56260 or email us at dllalim@hcinet.net Thank You Dale Lalim
