Garland police are looking for a small dark car from which several rounds were randomly fired Sunday at other vehicles, narrowly missing two children.
A similar shooting was also reported Sunday in Mesquite and a stop sign was shot up overnight Monday in north Garland.
"Of course anything getting shot at right now is getting looked at," said Officer Joe Harn, Garland police spokesman. "Both of the earlier shootings involved cars with little kids in them.
"And I tell you what: in one of them (a) baby came very close to getting hit."
The first shooting happened slightly before 5 p.m. Sunday at a red light on Buckingham Road, east of its intersection with Shiloh Road, Harn said.
The driver, a 22-year-old Garland man, was wounded in the hand and a 20-year-old woman, who was riding with him, was cut by breaking glass on her face and arms, Harn said.
Her 4-month-old daughter, he added, "was in a child safety seat in the back seat and was covered with broken glass but was not injured."
"The three were transported to Parkland Hospital of Dallas and will recover from their injuries," Harn said.
About four and half hours later, police got another call on Walnut Street, east of Plano Road.
A 37-year-old Dallas man told police he was sitting at the red light in his Dodge pickup with his 9-year-old son when he "heard gunfire and bullets coming through the driver's door," Harn said.
"The man was shot in the abdomen and was transported to Baylor Hospital of Dallas where doctors said his injuries were not life threatening," Harn said. "His son was not injured."
About a half hour later, Garland police received information that Mesquite police had a report of a vehicle being shot at as it exited Interstate 635 onto Oates Drive, but the victim in that incident was not hurt, Harn said.
"In all three incidents," he said, "the same basic suspect car description was given -- a small dark colored vehicle."
Harn said the shooter "is a male and of unknown race or age. Police believe the weapon used in each shooting was a pistol."
Harn said the stop sign that was shot up overnight Monday was on Centennial Drive, near where the first two shootings happened on Sunday.
A small dark car was stopped near the stop sign, but officers concluded that the driver was not a suspect in any of the shootings.
Anyone with information about the shootings can call the Garland Crime Stoppers tip line, 972-272-TIPS, Harn said. Callers may remain anonymous.
