The suspect is a white male in his 30s, Gerke said. He added that the incident began at a traffic stop. The suspect shot the trooper and then fled and eventually stole a mail truck.

According to the Texas Department of Public Safety, officers attempted to stop the suspect at around 4:13 p.m. ET. "Prior to the vehicle coming to a complete stop, the male driver (and only occupant in the vehicle) pointed a rifle toward the rear window of his car and fired several shots toward the DPS patrol unit. The patrol unit was occupied by two Troopers, and one was hit by the gunfire," the department noted.

The agency added that the trooper who was shot in the patrol vehicle was in stable condition. Two other officers who were shot were also in stable condition.

The Midland Police Department posted on Facebook around 6:30 p.m. ET that "there is no active shooter at this time" but Gerke encouraged residents to stay indoors.

CBS Odessa affiliate KOSA-TV reported the Music City Mall was evacuated. The station was told to "get away from the window" during live coverage. They described it as a "very chaotic scene."

The Odessa Police Department earlier posted on Facebook that there are "multiple gunshot victims" and at least one suspect driving around in a hijacked mail truck "shooting at random people."

"The suspect just hijacked a U.S. mail carrier truck and was last seen in the area of 38th and Walnut," the Facebook post read. "Everyone is encouraged to get off the road and use extreme caution! All law enforcement is currently searching for the suspect and more information will be released as soon as it becomes available."

The city of Odessa told KOSA-TV there have been 20 people injured.

"They are shooting at random," Midland Mayor Jerry Morales told The New York Times. "We have two fatalities and up to 20 injuries."

Texas Governor Greg Abbott said he will be traveling to Odessa on Sunday.
