A Palmer teenager suspected of throwing a rock that injured a woman sitting in a traveling car has confessed, officials say.


The 47-year-old woman was riding in a red Chevrolet Aveo, which was traveling south on Palmer Fishhook Road Sunday evening, when she was reportedly “struck by [a] rock after it broke the passenger door window where she was sitting,” according to an online dispatch from Alaska State Troopers.


The injured woman was taken to Mat-Su Regional Hospital, troopers wrote.


AST responded to the area of Palmer Fishhook Road near New Hope Street and were able to find evidence the rock had been hurled from a wooded area near the roadway.


Monday, troopers identified a 15-year-old boy of Palmer as a possible suspect. The teen “gave a full confession to his role in the incident,” the trooper dispatch said. Charges are being sent to the Division of Juvenile Justice for review.
