I'm trying to help a friend. She has a relative named Pfc. Ronald F. Sier, Co A, 1st Batt, 115th Inf, 29th Division who was killed in France on June 18, 1944.He wasn't returned home for burial in Monrovia, Frederick Co., MD until April 1948.Was this at all common for those soldiers whose remains were returned home? What was the reason(s)? Does anyone have any ideas at how she can pursue this? Thanks!
