DULUTH, Minn. (AP) — A 14-year-old Duluth boy is in custody in connection with the death of a 19-year-old family member.

Duluth police say officers responded to a medical call and found a 19-year-old woman injured and unresponsive. Officers apprehended the boy after he was “determined to be involved.” He is being held on suspicion of second-degree murder pending formal charges.

Officers had been at the same address earlier Friday. They had responded to a call of a disturbance, and an adult male member of the same family was alleged to have been assaulted. Police determined there’d been no assault, and left the scene.
