BAYTOWN, Texas -

Police officers shot and killed a suspect on a Baytown freeway Thursday.

Baytown police said Frederick Grayson, 45, had a domestic dispute with his girlfriend at an apartment complex in the 1300 block of East James about 10:45 a.m. He fired at least one shot and the woman called for help and Grayson, who was threatening to commit suicide, left, investigators said.

Officers spotted Grayson driving erratically on Texas Avenue and tried to pull him over, but he refused, police said. Officers chased Grayson as he pointed a gun to his head, police said.

Grayson hit another driver on Decker Drive before he pulled over on the same road, police said.

"Officers were unsure if he had taken his own life at that point," Lt. Eric Freed said. "They attempted to call him over the PA system to get him to exit the vehicle, but there was no response. Officers got on foot and approached the vehicle."

Detectives said officers found Grayson laying on his back inside the car and pointing his gun at them. They then called for SWAT officers.

"Within seconds, the driver's side window exploded," Freed said. "The suspect was shooting his handgun out of the driver's side window in the direction of officers. (He) even sat up and aggressively leaned his body outside the driver's side window."

Three officers then returned fire, killing Grayson, investigators said.

No officers were hurt.

The officers who fired shots have been placed on paid leave for the next three days, which is procedural.
