A 43-year-old man died after brandishing a firearm and threatening Rutherford County Sheriff's Office deputies outside his home late Wednesday night, Sheriff Mike Fitzhugh said.

Deputies responded to a domestic call about 9:38 p.m.in the 200 block of Breeze Drive at the Cascade subdivision near Walter Hill.

"They learned an armed man was in the house with three potential hostages," Fitzhugh said.

Two people exited the home but a third person was unable to leave because of medical reasons.

The Sheriff's Crisis Negotiations Team deputies started negotiations with the man, who has been identified as Allon Jones.

"After about one hour of negotiations, the man exited the house brandishing a firearm and officers engaged," Fitzhugh said. "The man is deceased. Our deputies were not harmed."

Medics took him to Saint Thomas Rutherford Hospital, where doctors pronounced him dead.

Tennessee Bureau of Investigation agents are investigating.

According to TBI's statement, this remains an active and ongoing investigation, as TBI Special Agents continue to work to gather any and all relevant interviews and evidence. As in any case, TBI's investigative findings will be shared with the District Attorney General throughout the process for his consideration and review.

As is TBI policy, the TBI does not identify the officers involved in these types of incidents and instead refers questions of that nature to their respective department.
