Chief Medical Examiner Jennie Duval determined that the cause of Mayo’s death was a gunshot wound to the head, and the manner of her death was homicide. The cause of McDonough’s death was a gunshot wound to the head, and the manner of his death was suicide.

Authorities said the two were known to one another and their bodies were found by police during a welfare check.
