John Dietz, 72, was named grand marshal of the parade after sharing his story with former Oak Park resident Marianne Trifone, who shared the story with the Community Relations Commission subcommittee in charge of the parade, The Chicago Tribune reported Thursday.

Doug Sterner, an Army veteran and military historian from Pueblo, Colo., said he and other experts found a number of discrepancies in Dietz's story. He said learning later Dietz claimed to have served under the name Diaz only caused more contradictions to come to light. "Our approach is to trust but verify," Sterner said. "It's a sad situation that when we see veterans or someone who appears to be a veteran, that there's a sense of suspicion about them." Advertisement
