Private First Class Harold W. Lee, 37 529 361, Army of the United States was reported missing in action as of 27 April 1945. No evidence of death was ever found and, of course, no remains were ever recovered. There's a memorial inscription on the Tablets of the Missing at the National Memorial Cemetery of the Pacific in Honolulu.
Records indicate he was a native of Missouri. I'll be in St. Louis next week and plan to spend a couple days or so at the Records Center. If you're near St. Louis and would like to join me, e-mail and I'll give you a number where you can reach me.
In the meantime, you can order his deceased file. You'll find practical instructions at Message #2112 (go back to the Main Page, enter "2112" in the box in the upper right corner that reads, "Jump to #____" then click on "Go").
