TUCSON, Ariz. -- Police have detained a person in the investigation into the shooting of a Tucson police officer outside a home during a burglary call.
The Tucson Police Department hasn't identified the "person of interest" who was detained in the investigation into the shooting of Sgt. Robert Carpenter and hasn't explained the person's possible involvement in the case.
No charges have been filed.
Carpenter was shot in the head while outside a home early Sunday morning during a burglary call. He remains in critical yet stable condition after undergoing surgery.
He was standing with other officers near the home after checking it following a report of a break-in. Then, officers heard a loud noise and saw Carpenter fall.
Police said they didn't see anyone in the area immediately after the 5:15 a.m. shooting, but they confronted a man at the scene about three hours earlier when responding to a separate burglary alarm at the same address. The man ran away, and officers couldn't locate him.
That man was described as a 20- to 30-year-old man who has a shaved head, weighs 160 pounds and was wearing a dark blue jersey with "43" on it. He also may have been wearing a red and white baseball cap.
