The Attorney General's office will investigate the apparent murder-suicide last week involving a veteran Rochester police officer and city 911 dispatcher.
Troopers say 43-year-old Melvin Williams shot and killed 34-year-old Janet Jordan at her Wetmore Park home last Tuesday.
Williams was later found dead of a self-inflicted gunshot wound in a vehicle in Henrietta.
The AG's Office of Special Investigation investigates every instance where a death may have been caused by a police officer.
