The Dent County Sheriff's Office is investigating a murder-suicide Sunday involving two brothers.

Investigators say the shootings happened in the community of Boss, just near the Dent and Iron Counties line. The brothers' mother called 911 about the initial shooting.

Officers found Phillip Tinker, 42, dead inside a home. He had died of a gunshot wound. Officers then saw the other brother, Dennis Dyer, inside another nearby home. After surrounding the home, officers then heard shots. They then noticed smoke coming from the home. After firefighters fought the fire, they found Dyer dead from a gunshot wound.

Investigators believe the altercation happened over a gun.

Sheriff’s Office is awaiting confirmation from the Boone County Medical Examiner’s Office for a positive identification. The fire marshal is also investigating.
