A candlelight vigil is held Tuesday for Tammy Meyers, who died after a shooting in Las Vegas. The description of how the road rage incident occurred has changed as details of the police investigation have been reported.

LAS VEGAS — A Las Vegas mother of four killed in a road rage shooting last week got in her car with her adult son and his gun and drove around their neighborhood looking for the person who ended up shooting her in a residential cul-de-sac, police said Tuesday.

In a change from earlier accounts, police Lt. Ray Steiber said 44-year-old Tammy Meyers had her teenage daughter run in the house to fetch her armed son, who then went with her as she drove to find the driver who had earlier stopped his car in front of hers, got out and approached her with angry words.

“Mrs. Meyers is scared, but she’s upset,” Steiber said, adding that the intent appeared to be “so they can find who frightened them on the roadway.”

“I would never say that anybody went looking for trouble,” Steiber said when asked to characterize Tammy Meyers’ five-to-10 minute drive through the neighborhood. He said she found, and for a time followed, the vehicle she had apparently been looking for.

Tammy Meyers then drove home, Steiber said, where a vehicle described only as a four-door gray or silver sedan pulled up and someone inside opened fire.

“Unfortunately I cannot say what was in Tammy’s mind,” the police lieutenant said. “Tammy is the victim.”

Steiber said the initial road rage incident happened while Tammy Myers drove slowly home from a school parking lot, where she had been teaching her teenage daughter to drive. The girl didn’t have a learner’s permit.

Steiber said the daughter told police a car sped up to them from behind and then pulled alongside. The daughter reached over from the passenger seat and honked the car horn at the car as it passed.

“She figured this person was speeding, and right or wrong, they needed to be corrected,” Steiber said of the girl, who he said is 15. “She honked the horn.”

Steiber pointed to a police artist’s sketch of a man sought for questioning.

“All indications to us are that this unknown person fired first,” Steiber said. He said Brandon Meyers returned fire.

Tammy Meyers was behind her son, and Steiber said police don’t believe he was responsible for the fatal shot. Tammy Meyers was wounded in the head and died Saturday after being taken off life support at University Medical Center. Steiber said no suspects have been identified or arrested.
