MINNEAPOLIS — Police say the gunman who killed at least four people inside a Minneapolis sign company had packaging for 10,000 rounds of ammunition in his house.

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. Dolan says police found the packaging during a search of Engeldinger’s house.
