(Undated) -- People are searching for answers following a shooting rampage at Fort Hood. Wednesday's shooting left four people dead, 16 injured and thousands struggling to come to grips with how and why it happened. The sprawling Texas military base was the scene of a 2009 shooting by an Army psychiatrist that left more than a dozen people dead. Very little is known about what led to this week's tragedy. The gunman has been identified as Army Specialist Ivan Lopez who was being treated for mental health issues.
