Three people were found shot to death in an Ardmore home this afternoon, and the man suspected in the killings later shot himself to death, authorities said.

The bodies of three adults were found around 2 p.m. Sunday at a home on the 27000 block of Pinedale Road, the Limestone County sheriff's office said. The names of the victims haven't yet been released.

All three died of multiple gunshot wounds, apparently from a rifle, said sheriff's spokesman Stephen Young.

Authorities began a search for Darwin Brazier, 43, who they said later shot and killed himself near his home on Cook Road in neighboring Madison County.

Brazier was the ex-husband of one of the victims, Young said. It is unclear what his relationship to the other two victims was.

After the bodies were discovered, authorities began searching for a red-over-silver 1997 Ford F-250, believed to be driven by Brazier. The vehicle was found in north Madison County on Macedonia Road at his father's home, authorities said.

Later in the afternoon, Madison County Public Information Officer Lt. Donny Shaw said authorities searched the Macedonia Road area with the K9 unit.

Investigators are at 27734 Pinedale Road in Limestone County, where three people were found shot to death Sunday, July 1, 2018.

Around 8:20 p.m., the Limestone County Sheriff's Office announced that Brazier was dead.

Madison County's SWAT team found Brazier's body, Shaw said. The team was conducting a search near the man's home, based on investigative information gathered by Limestone County deputies.

"The SWAT team believed they were receiving gunfire," Shaw said, but they soon found Brazier's body near his home.

None of the deputies was injured.

Today's fatal shootings bring the number of homicide victims in Limestone County to six so far in 2018.

Five people have been killed there in the past three days. Two people were shot at a home on Airfield Street in Athens on Friday. One man died at the scene; the second man was pronounced dead at Huntsville Hospital.
