In Miami, Rigoberto Alpizar, a passenger reportedly suffering from a mental disorder, was killed by federal air marshals Wednesday. Witnesses say Alpizar ran off the plane after claiming he had a bomb in his backpack, shortly before it was set to take off. His wife followed behind him, yelling out to bystanders her husband had not taken medication for a serious bi-polar condition. Air marshals shot Alpiza five times when he refused to lie on the ground. No bombs were found in the backpack or in any of the plane’s luggage. Alpiza and his wife were reportedly traveling back from a missionary trip in Peru. The shooting marked the first time federal air marshals have used their guns aboard planes since they were introduced following the September 11th attacks.
