Sue Messenger, a high school teacher in Fort Lauderdale, Florida, spent more than 20 years setting up fake crime scenes for her forensics course, complete with realistic looking skeletons and other evidence.

On Monday, she accompanied students of another such field trip, where they "oohed" and "ahhed" over the simulated corpses. "The first thing we thought was, 'That's a real good dummy she set up,'" said Juan Cantor, a 15-year-old student.

Alas, no, what the kids had found was the dead body of David Wayne Bodie, 45, a local homeless man who had "died of natural causes" in the park. Pay attention kids; that's probably going to be on the test.
