Upon arrival, a female victim advised deputies that during the altercation, Jackson McClain Chaney, 25, pointed a firearm at her. The victim was able to leave the residence unharmed.

 

Chaney refused to exit the residence, and deputies established a barricade. Members of the Emergency Services Team, Hostage Negotiations Team, and Criminal Investigations Division responded to assist.

 

After several hours, deputies obtained and served a search warrant on the residence. Chaney was taken into custody and transported to a medical facility for evaluation.

 

A Pistol Mitraliera Model 1963 assault rifle was recovered at the scene.

 

Following his release from the medical facility, Chaney was transported to the Detention and Rehabilitation Center in Leonardtown, where he was charged with first- and second-degree assault.

 

Chaney remains incarcerated pending a bond hearing.
