CARROLLTON, Texas — Police in North Texas shot and killed a man during an altercation at a gas station — later determined the gun was a replica.

On Saturday, October 5, 2019, around 5:30 p.m., the Carrollton Police Department responded to the RaceTrac gas station at 1716 West Frankford Road after receiving a 911 call about a man with a gun passed out in a vehicle in the parking lot.

A citizen told responding officers the man in the car was holding what appeared to be a revolver in his lap, according to a press release from the Carrollton Police Department.

"From a short distance, officers observed a white male in the driver's seat of a red car with the doors closed and the windows rolled up," stated the department. "Out of an abundance of caution, officers initially attempted to make contact with the man using a squad car public address system, but he remained unresponsive."

Paramedics were called to the scene and staged nearby.

"After repeated audible attempts to wake him were unsuccessful, a group of officers protected by a ballistic shield approached the vehicle in an effort to assess the man's condition," continued the statement. "When officers arrived at the car, they observed a handgun in the man's lap."

The man woke up as officers attempted to open the car door and secure the handgun.

"After initially complying, the man suddenly reached down, picked up, and raised the gun," stated the department. "One officer then fired his duty weapon, striking the man."

The man, identified by police as 33-year-old Christopher Massey of Allen, Texas, was transported to Medical City Plano where he was later pronounced deceased.

Carrollton police later determined the handgun to be a replica firearm.

The Carrollton Police Department had no prior interactions with Massey, according to the release.

The officer who fired his weapon has been with the Carrollton Police Department for four and a half years, has prior law enforcement experience, and has been placed on routine paid administrative leave.

The Federal Bureau of Investigation's Evidence Response Team and the Frisco Police Department's Crime Scene Unit responded to assist in processing the scene, at the request of the Carrollton Police Department.

The incident was recorded on officer-worn body cameras and the case has been forwarded to the Denton County District Attorney's Office for review, according to the department.
