A driver crashed on Interstate 635 in Garland after being shot Monday night, police said.

The 37-year-old man, driving a 2007 black Chevrolet Avalanche, struck the inside barrier of the northbound lanes near Centerville Road about 9 p.m., Garland police spokesman Pedro Barineau said.

He was transported to a hospital with life-threatening gunshot wounds, but a surgeon later said he was stable.

"We've got to talk to him," Barineau said.

Police are investigating whether the incident is connected to reports of gunfire at Interstate 30 and Broadway Boulevard about 15 minutes before the victim was found, Barineau said. Officers recovered a shell casing on the highway.

No suspect information is available.

This summer in Dallas-Fort Worth, there have been both road rage-related shootings and isolated shootings of drivers by suspects who knew them. It's unclear what happened in this case.
