A husband and wife were killed in an apparent murder-suicide at a residence in Florida.

Police responded to a report of a shooting at a home in Bradenton, a city about 45 miles south of Tampa, on the morning of Thursday, Oct. 22, shortly before 8 a.m. local time, according to a press release from the Bradenton Police Department.

Upon arriving at the scene, officers discovered the bodies of married couple Phillip Edmond McClure, 60, and Brenda Gail McClure, 74, who died in an apparent murder-suicide.

The two were estranged at the time of their deaths, per police.

A motive has not been released at this time, and it is not immediately clear who called police.

Authorities said the investigation into the incident is still ongoing.
