Here's his marker. Henri-Chapelle American Cemetery and Memorial Henri-Chapelle, Arrondissement de Verviers, Liège, Belgium Grave Memorial Records - Find A Grave
Also found him on page 20/56 on here. an Alphabetical list of 8th Infantry Division Battle Deaths Says DOW = Died of Wounds http://www.fatherswar.com/8thinfdiv/WW2/ww2_8thgeneralinfo/8TH_INF_DIV_KIA_LIST.pdf
So I looked up the division, and on February 23, 1945 they crossed the Rur river. I guess that is where he died.
If you haven't already found it, this link takes you to the 28th's AAR for Feb, 45. Covers the Roer crossing on the 23rd on page 7, it sounds brutal. http://www.fatherswar.com/8thinfdiv/WW2/ww2_28thinf/28_INF_AAR_FEB_1945.pdf
