MINNEAPOLIS (AP) - Police say the gunman who killed four people inside a Minneapolis sign company had been fired hours before the attack.

Minneapolis Police Chief Tim Dolan told a Friday afternoon news conference that the gunman in Thursday's attack was 36-year-old Andrew J. Engeldinger of Minneapolis.

Engeldinger opened fire Thursday afternoon at Accent Signage Systems. He was among five people found dead at the scene of the small sign-making company on the city's north side. Police say he killed himself after the attack.

Dolan says police found packaging for 10,000 rounds of ammunition during a search of Engeldinger's house.
