LAS VEGAS (AP) — With the suspected gunman in jail, police focused Friday on finding an accomplice in what they have portrayed as the road-rage killing of a Las Vegas mother outside her home.

The arrest of 19-year-old neighbor Erich Milton Nowsch Jr. — and the disclosure that the shooting victim, Tammy Meyers, had taken a motherly interest in him following the suicide of his father five years ago — provided another twist to a case that has posed more questions than answers since the bloodshed Feb. 12.

District Attorney Steve Wolfson said that despite "a lot of twists and turns in the case," he is confident police have the right man. He said he expects at least one more arrest in the coming days.

Police remained tight-lipped about their efforts, a day after homicide Capt. Chris Tomaino told reporters that pieces of the puzzle would fit together once the case is turned over to prosecutors.

Tomaino identified Nowsch as the suspected gunman and said a sketch that had been circulated early in the investigation was no longer relevant.

Neighbors noticed when the 5-foot-3 Nowsch was taken into custody Thursday that he looked nothing like the 6-foot blond man police had described earlier.

Nowsch was arrested after SWAT teams surrounded his house a block from the Meyers home, in a middle-class neighborhood of modest stucco homes with tile roofs about 5 miles west of downtown Las Vegas.

Police and Meyers family members have characterized the case as a road-rage confrontation that began while Tammy Meyers gave a late-night driving lesson to her 15-year-old daughter, and ended with a shooting in a cul-de-sac in front of the Meyers home.

But the arrest of an acquaintance seemed to cast the case in a different light.

"We know this boy," Robert Meyers, husband of the slain mother of four, said Thursday.

"I couldn't tell you this before," he added. "He knew where I lived. We knew how bad he was, but we didn't know he was this bad."

Meyers did not elaborate.

Melissa Mours, a next-door neighbor of Nowsch's, said Thursday she saw Robert Meyers and at least one of his three sons at the Nowsch home on Sunday. Erich Nowsch wasn't there, Mours said.

Meyers said his 44-year-old wife helped nurture Nowsch after the boy's father died in 2010 — meeting him in a neighborhood park, giving him money and food, consoling him and urging him to "pull his pants up and be a man."

The coroner ruled Erich Milton Nowsch Sr.'s death a suicide from carbon monoxide poisoning. His autopsy also found cocaine and the over-the-counter pain and cold medication in his body.

Nowsch was jailed for a court appearance on Monday on charges including murder, attempted murder and firing a gun from a vehicle. It wasn't clear if he had a lawyer.

Tammy Meyers was removed from life support on Sunday as donations for her funeral costs poured in to a fundraising site.

The sympathy turned into skepticism and the fundraising site was shut down after police revealed Tuesday that Tammy Meyers wasn't actually followed home after the initial road confrontation.

She instead dropped her daughter off and picked up her 22-year-old son, Brandon, armed with his 9mm handgun, to try to find the driver who had frightened her.

They found the vehicle and followed it for a time before heading back home, police said. That's when the silver car pulled outside the Meyers home and a shootout erupted, police said. Brandon Meyers said he fired back to protect his family.
