The Kentucky State Police, which is investigating the shooting, said that another person who is not an officer had also been shot during the episode and that a police dog had been struck and killed. An additional officer sustained an injury unrelated to gunfire, Capt. Paul Blanton of the Kentucky State Police said in an interview.
The law enforcement officers who were killed were identified by the authorities as Capt. Ralph Frasure of the Prestonsburg Police Department, Deputy William Petry of the Floyd County Sheriff’s Department and a dog handler, Jacob R. Chaffins of the Prestonsburg Police Department.
Two of the officers who were shot remained in the hospital on Friday, the authorities said. One was treated and discharged. The non-officer was receiving medical care at a hospital, but a precise condition was not immediately known.
Sheriff John Hunt of Floyd County told The Herald-Leader that it appeared that Mr. Storz had been waiting for officers and had opened fire without warning.
Allen, a town of fewer than 200 residents about 120 miles east of Lexington, does not have its own police force, so officers from nearby agencies, including the Floyd County Sheriff’s Department and the Prestonsburg Police Department, responded to the home, the authorities said.
