The Huntsville Police Department has identified the man shot and killed Saturday during a confrontation with police in a Jordan Lane parking lot.

William Thomas Hennessey, 34, of Huntsville was pronounced dead at the scene, located at 1004 Jordan Lane. Investigators say that Hennessey was shot by a Huntsville patrol officer after he pulled a gun on an Alabama state trooper.

Lt. Stacy Bates, a police spokesman, said the incident began around 9:30 a.m. Saturday when officers responded to a call to help Alabama state troopers locate a possible drunk driver in a blue Volkswagen. Another driver was following the car, which was believed to be the same one that struck mailboxes on Highway 53 a short time earlier in Madison County.

The officers and troopers found the car in the parking lot a short time later, but the driver was not inside and, upon checking the area, the officers could not find him. A trooper was flagged down by citizens a few minutes later to say that the man, later identified as Hennessey, was back inside the car.

When the trooper approached Hennessey, who was seated in the passenger side of the Volkswagen, a struggle began and Hennessey pulled a gun. A Huntsville officer passing by spotted the fight and rushed in to assist, Bates said.

"Hennessey continued to fight with both the officer and the trooper and refused to drop the weapon. The Huntsville police officer fired his weapon and Hennessey died at the scene as a result," Bates said.

The incident was captured on Huntsville Police Department body cameras and dashboard cameras, Bates said.

"The investigation is ongoing and the findings will be presented to an Incident Review Board in the coming weeks," he said.

Review boards consist of members of the Huntsville Police Department, the Madison County District Attorney's Office, the Alabama State Bureau of Investigation, and members of the city's Police Citizens Advisory Council, among others. Findings are made public after the review is complete.

Court records show that Hennessey had a history of drug and alcohol-related arrests, but just one conviction in 2011 of possession of a controlled substance. He was placed on probation.

Hennessey was arrested again in February for shoplifting and on May 31 for possession of drug paraphernalia, according to Madison County Jail records.
