Members of the Phoenix Police Department SWAT team exit the garage at the home of a suspected gunman who opened fire at a Phoenix office building, wounding three people, one of them critically, and setting off a manhunt that led police to surround his house for several hours before they discovered he wasn't there, Wednesday, Jan. 30, 2013, in Phoenix.  Authorities believe there was only one shooter, but have not identified him or a possible motive for the shooting. They don't believe the midmorning shooting at the complex was a random act.
