Postal Shooting Rampage

A former postal worker shot five people to death at a huge mail-processing center and then killed herself in what was believed to be the nation's deadliest workplace shooting ever carried out by a woman. The attack Monday night was the biggest bloodbath at a U.S. postal installation since a massacre 20 years ago.

Investigators would not release the killer's name or discuss a motive or the circumstances under which she left the Postal Service two years ago.

The rampage -- the nation's first deadly postal shooting in nearly eight years -- sent employees running from the sprawling Southern California complex and prompted authorities to warn nearby residents to stay indoors as they searched for the killer.

Authorities found two people dead outside the plant, blocks from the University of California, Santa Barbara. Another body was just outside the door, and a fourth was just inside. Two more bodies -- including that of the killer -- were farther inside. A sixth person was in critical condition with a gunshot wound to the head. All of the woman's victims were believed to be employees at the postal center. The woman reloaded her 9 mm handgun at least once during the rampage.
