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&#039;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&#039;t believe the midmorning shooting at the complex was a random act.
