The confrontation began after Michael Koch Boyd's sister posted a note on his bedroom door requesting he move out of the residence they shared.

FORT WALTON BEACH — A domestic dispute that resulted in a standoff late Friday night has landed a Fort Walton Beach man in jail.

According to an Okaloosa County Sheriff's Office news release, deputies responded to a residence on NW Doyce Drive around 9 p.m. Friday for a domestic dispute that erupted between 52-year-old Michael Koch Boyd and his sister.

In his arrest report it was noted the confrontation began after Boyd's sister posted a note on his bedroom door requesting he move out of the residence they shared.

During an ensuing argument, the sister told deputies that Boyd produced a small handgun and began pointing it at her head while screaming a threat to kill her. There was a short struggle for the handgun that followed before the sister was able to grab her young child and flee the residence.

When deputies arrived, Boyd refused to exit the home, where a roommate and Boyd's wife remained inside, presumed to be held captive, according to the release. The roommate was eventually rescued from a second-story window by OCSO deputies.

OCSO’s Special Response Team and Crisis Negotiations Unit responded to the scene to assist. Several hours of negotiation led to Boyd surrendering peacefully and his wife unharmed.

Boyd was initially transported to Fort Walton Beach Medical Center after complaining of pain following his surrender to deputies. After being medically released, he was booked into the Okaloosa County Jail at 7:35 a.m. Saturday on charges of aggravated assault with a deadly weapon without intent to kill-domestic violence and simple assault with intent/threat to do violence.

Boyd is currently being held without bond, according to the jail website.

Deputies completed a search warrant at the NW Doyce Drive home and found Boyd's gun, holster and some ammunition, according to the release.
