Concord, NH –Attorney General Gordon J. MacDonald, New Hampshire State Police Colonel Christopher J. Wagner, and Hollis Police Chief Joseph Hoebeke announce that autopsies were conducted on Brian McDonough (age 51) and Alisa Mayo (age 41), who were discovered dead inside the same residence in Hollis, New Hampshire, on March 30, 2019.

Chief Medical Examiner Dr. Jennie V. Duval has determined that the cause of Ms. Mayo's death was a gunshot wound to the head, and the manner of her death was homicide. Dr. Duval has determined that the cause of Mr. McDonough's death was a gunshot wound to the head, and the manner of his death was suicide.
