Authorities are investigating after a Madison Township man was shot and killed by SWAT officers following a standoff Wednesday night.

Officials identified the man as Benjamin Ailstock, 38.

According to the Lake County Sheriff's Office,  Ailstock barricaded himself in a Hazel Avenue home and officers were called around 11:30 p.m. Ailstock spent five hours in the home and refused to negotiate with authorities. 

Ailstock was shot and killed when he charged from the home brandishing a handgun to confront SWAT officers.

The incident started when a domestic dispute between Ailstock and his wife became physical. The wife told dispatch she had gathered her husband's guns and locked them in the car, but he knew they were there.

Ailstock was released from a hospital four days prior to his death. His wife told authorities he was there for detox and continued drinking when he returned home. 

When officers first arrived, Ailstock answered the front door with a handgun, but closed the door on police. Once SWAT arrived on scene, Ailstock dropped a shot gun from a rear window and attempted to leave the house. Unable to do so, he climbed back inside the window. Officers recovered the shot gun and found it loaded with deer slugs.

According to the Lake County Sheriff's Office, Ailstock suddenly emerged from the front door brandishing a handgun. He refused demands to drop the weapon and authorities say he raised his gun before he was shot. He was taken to Madison Medical Campus, where he was pronounced dead.
