officer-involved shooting

Both shootings happened in the greater Twin Cities area.

Investigators say the 14-year-old had a butcher knife.

The man and officers fired shots, the sheriff's office says.

Tensions are high in St. Louis after a former police officer was acquitted on murder charges.

The county attorney said his office has gotten calls demanding charges now.

The witness had been biking through the area at the time of the officer-involved shooting.

The Minnesota Department of Public Safety Bureau of Criminal Apprehension is investigating.
