SEATTLE - Mount Rainier National Park in Washington will reopen to the public on Saturday after it was shut down following the shooting death of a park ranger originally from New Jersey.

Authorities say Ranger Margaret Anderson, a Westfield native, was shot to death on New Year's Day trying to stop a car that failed to pull over at a checkpoint requiring drivers to put chains on their vehicles.

Authorities say she was killed by Benjamin Colton Barnes, a 24-year-old Iraq war veteran. Investigators found his body face down in a snowy creek Monday with a handgun and rifle nearby. An autopsy Tuesday showed he had hypothermia and drowned.
