New information released by Las Vegas police has changed the initial narrative of a fatal shooting in an apparent "road rage" incident.
Police arrested Erich Nowsch on Thursday, accusing him of killing Tammy Meyers last week, and detailing how he allegedly confessed to his friends about his involvement in the shooting.
Here is a revised timeline of events surrounding the shooting:
Thursday, Feb. 12: Meyers' 15-year-old daughter told police she and her mother were on their way home from a driving lesson when they encountered someone near their house. In the apparent "road rage" incident, the driver got out of the car and said, "I'm gonna come back for you and your daughter," according to a police complaint released Friday. Police have not said whether that person was Nowsch or a second suspect.
After Meyers, 44, and her daughter arrived home, Meyers' son Brandon, 22, "told his mother to come in the house and call the police; but she told him no, come with me or I will go by myself," police said.
Authorities said the mother and son - who was armed - went out to search for the driver. The suspect then allegedly followed them home and shot Meyers in her driveway, according to police.
Earlier this week, police reported that the suspect fired first and Brandon Meyers returned fire.
Saturday, Feb. 14: Meyers died at the University Medical Center of Southern Nevada.
Tuesday, Feb. 17: Nowsch, the suspect in the shooting, was first questioned by police on Tuesday while he was in juvenile detention on an unrelated warrant, police said. While Nowsch did not match the physical description of the suspect, according to police, his alibi did not check out when he was questioned about her murder when his name was brought up in the investigation.
Nowsch denied involvement, police said.
Thursday, Feb. 19: After a two-hour standoff, Nowsch was arrested and charged with murder, attempted murder, and illegal discharge of a gun in connection with Meyers' death.
The shooting was initially described as a random incident, but Nowsch knew the Meyers family and lived one block away, according to Bob Meyers, Tammy Meyers' husband.
Meyers said his wife had spent "countless hours" at a park in their neighborhood, Ansan Sister City Park, "consoling this boy."
"She was really good to him," Meyers told reporters Thursday. "She fed him, she gave him money, she told him to pull his pants up, and to be a man more times than I can count. But none of you knew this before because it would have hurt what these great Metro detectives were trying to accomplish."
Police said they only learned of the relationship between the Meyers and Nowsch hours before his arrest.
"I couldn't tell you this before, he knew where I lived," Meyers said to the reporters, adding that he knew "a few things" about the case but couldn't divulge the information earlier.
According to information released by police Friday, a friend of Nowsch said the 19-year-old admitted to his involvement in a shooting. Nowsch said he thought people in the car were looking for him and thought he saw a gun, which prompted him to fire 22 times, police said.
Nowsch told them he "got those kids, they were after me, and I got them," according to the complaint. He also said no one had fired at him.
Nowsch told his friend that someone had threatened his mother and her newborn, police said, and that "if it gets heavy here he was going to Arizona."
Police said they are looking for a second suspect, possibly the driver.
Nowsch's family has not returned an ABC News request for comment and his lawyers said they have not seen their client yet.
Nowsch is scheduled to make his first court appearance Monday.
