FREDERICK, Md. (AP) — A court document indicates Frederick County sheriff’s deputies fired at least 18 shots at a Mount Airy teenager who was killed after police say he refused to drop a shotgun.

The Frederick News-Post reported Tuesday on court documents stemming from the raid last week at 19-year-old Daniel Vail’s apartment.
