The Imposter
Surely the most bizarre true story I have heard in a long time. A 13 year old boy goes missing in Texas in 1993. 3 years later a 23 year old Frenchman impersonates him and travels to the USA to meet his 'family'. I'm not sure what was more bizarre, the fact that he did that or that fact that the family believed him. He didn't even look like him.
