TACOMA, Wash. -

Officials at Mount Rainier National Park are observing a moment of silence at 10:44 this morning to honor slain park ranger Margaret Anderson.

The 34-year-old was shot and killed Jan. 1, 2012 as she tried to stop a man who drove through a tire chain checkpoint near Longmire. The body of the suspect was found the next day about a mile away in the snow. He drowned in a creek while affected by hypothermia.

Anderson was hailed as a hero for stopping the gunman from reaching a congested, popular visitor area that day.

The mother of two girls joined the Park Service in 2002. She and her husband, Eric, also a park ranger, transferred to Mount Rainier in 2008.

The News Tribune says the family has moved but KeyBank in Eatonville maintains a donation account in her name.
