New details emerging about an alleged road rage incident between a mother and a young man that ended with her getting fatally shot are starting to take a different turn altogether, police say.

The details, at first, seemed clear: a Las Vegas mother of four had just finished giving her 15-year-old daughter driving lessons when they encountered a driver on the way home, a driver that eventually followed them home and gunned the woman down in front of her house. However, a police report released yesterday indicates that 44-year-old Tammy Meyers may have been involved in a case of a neighborhood dispute with her killer, rather than a simple road rage incident between strangers, according to an Associated Press report.

Police have since arrested 19-year-old Erich Milton Nowsch Jr., who is suspected of pulling the trigger, and far from being a stranger to Meyers, he lived less than a block away and attended the same high school as Tammy Meyers’ two sons from 2011-12. In fact, Meyers tried to counsel the young man after his father committed suicide five years ago.

Nowsch isn’t believed to have been behind the wheel nor did he tell his friends he was upset about a traffic encounter, police say. Instead, he said he thought someone was after him, the police report states.

Authorities didn’t reveal why they suspected Nowsch was the shooter, but the police report indicated he had been questioned on Tuesday, about five days after the shooting and after Meyers had been taken off life support.

Nowsch allegedly told his friends after the shooting when he was a passenger in a car, he saw someone in a green car wave a gun at him and thought he was in danger.

Meyers, meanwhile, had taken her daughter, Kristal, to a school parking lot to practice driving in her green sedan. After practicing on some nearby residential streets, Meyers took the wheel to head home, which is when a silver car suddenly sped up behind them and pulled alongside. Kristal honked the horn as her mother drove, according to the report.

The silver car chased them through the neighborhood before spinning out sideways in front of them. A man came out and said, “I’m gonna come back for you and your daughter,” the report states. She hit the gas and sped past the car on her way for home.

When she thought she saw the car again after arriving home, she had Kristal get her 22-year-old son, Brandon, who grabbed a 9mm handgun. He then accompanied her to drive to the place where the silver car had blocked her path, and then headed home when they spotted the silver car. After following the car for a few blocks, they passed the school again, and then the silver car stopped on the road, and then someone started shooting on the passenger side, Brandon said.

They fled back home, and as they pulled up, Brandon saw headlights approaching the cul-de-sac where they lived. As the car got closer, someone opened fire, Brandon told police. He returned fire, causing the car to back out and disappear. His mother was lying on the ground with a head wound, prompting him to call 911.
