A federal agent died and two other law enforcement officers
were injured in a shooting on an Amtrak train at a station Monday
morning in Tucson, Arizona.
Members of a regional
narcotics "alliance" of local and federal authorities were conducting a
routine check on a stationary train when a man opened fire, Tucson
Police Chief Chris Magnus said Monday. Authorities were detaining
another man on the train's upper deck when the shooter pulled out a
handgun, he said.
