MEMPHIS, Tenn. — The deadly mass shooting in Holly Springs, Mississippi on Sunday has been ruled as a “murder-suicide”, according to the Marshall County Sheriff.

“Based on the evidence we have collected, based on the forensic interview of a child witness that was present when this tragedy occurred, it is my opinion at this time that it was a murder-suicide,” said Kenny Dickerson, Marshall County Sheriff.

The four victims have been identified as a man and a woman from Holly Springs and two women from Memphis.

The Violent Crimes Task Force, which assisted in the investigation, is made up of two deputies and two Holly Springs Police Officers.

“Their job was to photograph, mark, and collect evidence and then there was another team assigned to try and locate any kind of video footage that someone may have caught on their phone cameras or their Ring cameras,” said Kelly McMillen, Marshall County Sheriff’s Office Commander.

Holly Springs elected officials say the task force is a plus for the community.

“A collective team that could come together and help us solve crime, especially violent crime, and solve them in a timely manner,” said Bernita Fountain, Holly Springs Alderwoman Ward 1.

Sheriff Dickerson says he is now frustrated that even after the task force worked tirelessly to gather forensic evidence and determine a motive in these shootings, it may take days now for the State Crime Lab to come back with an official cause of death.

“To say 100%, we will not know that until we get the professional forensic autopsy results in our hands,” Sheriff Dickerson said.

Marshall County officials also say two of the shooting victims shared a child, a three-year-old girl, who was not injured and is currently in the care of family members.
