Dallas - Two drivers were shot to death and a third injured on roads in northeast Dallas and Garland during rush hour Monday evening.

Police were investigating four incidents Monday after the first fatal shooting was reported about 5:40 p.m. in Garland just north of LBJ Freeway. Police are working to establish whether the three shootings in Dallas are related to the Garland one.

"For whatever reason, this person is upset with something or someone and he's taking it out on innocent victims going down the road, and that's very scary," said Dallas police Sgt. Gil Cerda.

The first victim was a man driving a small two-door car on Jupiter Road, police said. He stopped at a red light at Marquis Drive and an extended-cab Ford F150 pickup pulled up alongside his car. A balding white man in his 40s fired several shots at the car's driver, killing him, said Officer Joe Harn of the Garland police.

Police said the pickup fled south on Jupiter Road. Minutes later it was reported that a man began shooting at a semi with no trailer on LBJ between Royal Lane and Skillman Street. No one was injured.

Police said a driver then shot at a 42-year-old man driving a United Van Lines 18-wheeler. The trucker, William Scott Miller, 42, of Frankfort, Ky., was killed. His rig came to a stop in the middle lane of westbound LBJ just east of the Miller Road exit.

Police have not released the names of the men who were killed but said the driver of the 18-wheeler was about to park his rig.

"The plan was he was going to fly home to be with his wife and kids," said Lt. Craig Miller of the Dallas homicide unit.

Farther west on LBJ near Skillman Street, another truck was struck by bullets the fourth incident. That driver was struck by flying glass, said Jesse Medford, terminal manager with Dugan Truck Line. The driver was taken to an area hospital.

Mr. Medford said the driver, his employee, radioed him saying, "I'm getting shot at! I think I'm shot!" The trucker said he didn't know why he was being fired upon, Mr. Medford said.

Mr. Medford told his driver to pull over, then Mr. Medford called 911.

Mr. Medford did not identify his driver other than to say he's a longtime trucker in his 40s. He said the driver told him that he did not know who was shooting and did not give a detailed description of the assailant.

"He didn't say anything about any type of road rage," Mr. Medford said.

Rush hour traffic slowed to a crawl along the highway as police shut down all westbound lanes of LBJ east of the homicide scene for several hours. Drivers used access roads and alternate routes to get home as authorities began an intense investigation at the site.

Investigators with flashlights were scouring the empty westbound lanes, looking for bullet casings and other evidence.
