A teenage suspect has been arrested in connection with fatally shooting a mother of four after a road rage incident last week, police said Thursday.

"It is believed right now he is the only shooter, but there is another suspect involved in the incident," Las Vegas Metropolitan Police Department Capt. Christopher Tomaino said.

Erich Nowsch, 19, was arrested early Thursday afternoon after a brief standoff at a home a block away from the scene of the Feb. 12 shooting.

Police said Nowsch shot Tammy Meyers, 44, outside her home around 11:22 p.m. that night, and she died two days later. He faces charges of murder, attempted murder and discharging a gun in a vehicle.

The shooting occurred after Meyers was confronted by an angry driver in a road rage incident earlier that night, as she was heading home with her daughter.

Police said that after Meyers got home, she and her 22-year-old armed son went out looking for that driver and followed a car she believed was the same as the one involved in the earlier incident. They stopped following that car and went back home, and that's when a silver or gray car pulled up and someone inside began shooting, police said.

Meyers’ husband, Robert, said the family is familiar with the suspect.

"We know this boy. I couldn't tell you this before," Robert Meyers told reporters outside his home after the arrest. "He knew where I lived. We knew how bad he was, but we didn’t know he was this bad."

Robert Meyers said his wife "spent countless hours at that park consoling this boy," that she fed him and gave him money, and that "she told him to pull his pants up and to be a man, more times than I can count."

Meyers’ son shot back after the gunman opened fire on them that night, police said. The firearm her son used is properly registered, according to authorities.

"I did what I had to do to protect my family. Everyone can think what they have to think; I did it for a reason. And I'd do it for anyone I love," Meyers' son, Brandon, said at a vigil Tuesday.

Nowsch also had firearms registered to him, Tomaino said. He did not specify how many weapons Nowsch had or what kind they were.

As Nowsch was apprehended on Thursday, Robert Meyers lashed out at reporters, saying, "Are you happy? you made my wife look like an animal, and my son! There’s the animal! A block away! Are you happy?"
