Investigators look for a motive in a deadly mass shooting at Minneapolis church

MINNEAPOLIS (AP) — The shooter who killed two Catholic school students and wounded more than a dozen children sitting in the pews of a Minneapolis church once attended the same school and had been a member of the church, the city's police chief said.

Authorities were poring over videos, writings and the movements of the shooter but remained uncertain what motivated 23-year-old Robin Westman to open fire through stained-glass windows as children celebrated Mass on the first week of classes at the Annunciation Catholic School.
