Authorities say three more teens have been charged as adults with first-degree murder in the death of a Maryland police officer.

Baltimore County State's Attorney Scott Shellenberger says 15-year-old Darrell Jaymar Ward, 16-year-old Derrick Eugene Matthews, and 17-year-old Eugene Robert Genius IV are charged in the killing of Officer Amy Caprio.

The three were scheduled to appear at bail hearings Wednesday.

A fourth suspect, 16-year-old Dawnta Anthony Harris, is also charged with first-degree murder and is being held without bond. The Associated Press does not ordinarily identify underage suspects unless they face adult charges.
