... the guy threw himself in the river because some people thought he looked like someone who committed a crime that had nothing to do with him?
He went missing March 16. What makes you think he wasn't dead before April 15?

No, not if he was dead before the event took place. And besides, suicide due to mistaken identity? Why didn't the other guy go hang himself when people thought he did it. He went to the police to clear his name like any normal person would do. This guy was missing for a month. He was probably dead long before the Boston Marathon.
