The mystery of what happened to 25-year-old Columbia student Toby Cohen is still somewhat of a mystery, even to him. After word came in that he was found yesterday, the NY Sun is reporting on some of the finer details today. When the family called Columbia with fears he'd gone missing, they found out their son had withdrawn in the last month. Cohen, who had left his epilepsy medication at home the night he went missing, was discovered in upstate New York. More specifically, he was "found swimming in a reservoir in Carmel, N.Y., with bruises on his face and legs and disoriented from missing doses of medication." He has no recollection of how he got there, or of any recent events, but is expected to make a full recovery.
