Police have discovered the bodies of a man and a woman inside a home in the 2100 block of Rockwell Court following an hours-long barricade in Catonsville.

Police were initially dispatched around 10:19 a.m. after a 3rd-party caller informed 911 that they believed there was a suicidal subject inside the home with a gun. Police initiated a barricade situation, closing surrounding roadways, while they attempted to investigate and resolve the situation. Once police were able to safely enter the dwelling they discovered the bodies of both victims, which have not yet been identified.

The Baltimore County Police Homicide Unit continues to investigate this incident as a murder-suicide, and to determine the relationship between the deceased man and woman.
