Nathan Posso, 32, was found dead in Minneapolis on January 9, 2014. The Minneapolis Police Department continues to seek information from anyone who might have leads.

Friends and acquaintances offer a different account, saying Posso took his own life in a downtown office building and describing him as sad, lost and tired. He was remembered as funny and charismatic, and had lost much of an arm in a freight-train accident. In his memory supporters raised funds, with a substantial donation going to a homeless youth center.

What details might help move this case forward for those who knew Nathan or were in the area that day?
