WWII Soldier Killed at Parade Honoring Veterans

BOSTON (Reuters) - William Hammond survived one of the bloodiest battles of World War II but died at a parade honoring him and others after a van at a Veteran's Day parade ran over him.

This happened just a mile or two up to road from where I work.

And to add to the irony, the van in question is owned by the local Veterans of Foreign Wars chapter.
