Campers killed by tree limb in Yosemite were teenage boys

SAN FRANCISCO (AP) — Two young campers killed by a falling tree limb in Yosemite National Park have been identified as two 14-year-old boys from Orange County in Southern California.

The Mariposa County Sheriff's Office identified the boys as Justin Lee of Irvine and Dragon Kim of Tustin.

Assistant Coroner Andrea Stewart said it appears the boys were crushed to death. They died immediately, she said.

The boys were sleeping in a tent when a limb fell from a black oak tree about 5 a.m. Friday in the Upper Pines Campground in Yosemite Valley, a parks spokesman has said. The campground is one of the park's most popular, with a view of Half Dome.

Park rangers alerted by a 911 call arrived to find the boys dead.

It is unclear why the limb fell.
