Immediately after Sunday's shooting, police cleared out the park of visitors and mounted a manhunt.

Scene of the crime: A police officer examines the car that the shooting suspect was driving at Mount Rainier National when he was stopped by Park Ranger Margaret Anderson . Park superintendent Randy King said . Anderson, a 34-year-old mother of two young girls who was married to . another Rainier ranger, had served as a park ranger for about four . years.

Anderson's in the small town of Eatonville, Washington, said the . ranger's family moved in about a year ago. He said they were not around much, . but when they were Norton would see Anderson outside with her girls. 'They just seemed like the perfect family,' he said.

The NRA said media fears of gun . violence in parks were unlikely to be realised, the NRA wrote in a . statement about the law after it went into effect. 'The new law affects . firearms possession, not use,' it said. The group pushed for the law saying people have a right to defend themselves against park animals and other people.
