'Road Rage' Shooting: Inside the Life of the Mother Gunned Down

— -- The family of a Nevada woman who was gunned down in front of her home after what police described as a road rage incident is grieving their loss and expressing sadness that her young grandchild will grow up without her.

Tammy Meyers died Saturday night after being shot late Thursday evening after taking her teenage daughter to practice driving at a school parking lot in Las Vegas, authorities said.

Meyers, 44, had four children and one grandchild, and now the family is grappling with what their life will be like without her.

Meyers' son Matthew, 19, told ABC News his 14-month-old son "now I've got to deal with my son growing up without knowing his grandmother."

Matthew said the family had been celebrating his birthday just hours before the shooting.

"My sister is really emotionally destroyed right now," Matthew told ABC News.

"My sister and my brother are taking blame for everything that happened because they were the only ones here," he said.

Matthew Meyers explained that his mother and sister were going the speed limit, 25 mph, when the driver of another car got annoyed that they were going too slow and sideswiped them as he tried to pass.

Tammy Meyers' husband, Robert Meyers, said another one of their sons, a 23-year-old, reportedly came out of the house and began firing back at the car, according to The Associated Press, although Las Vegas police are still trying to sort out who fired first.

Robert Meyers told police he believes at least one of his son's shots hit the other car.

Matthew Meyers said his older brother ran out with his gun after his sister ran into the family home to say that a car was following them.

"My brother protects my mom, he has a concealed weapon," Matthew said.

"My brother saw the gun, he started popping shots at the dude," Matthew said, noting that it’s still unclear who fired first.

Meyers had taken her daughter, whose name has not been released, on Thursday night as part of her practice before getting her driver's license.

The driving lesson reportedly took place at a nearby school and while it is unclear what actually happened with the other driver, something prompted the suspect to follow Meyers and her daughter home.

According to the family's GoFundMe page, Meyers worked as a nurse and dedicated herself to "selflessly helping others in need," even after death, though she is not registered in the Nevada State Board of Nursing. Her relatives decided to donate her organs "and providing the gift of life to those in need."

Public records show she previously lived in California, but she is not listed on that state's registry of nurses, either.
