Two students who died when a tree limb fell on top of them in Yosemite National park have been identified as Dragon Kim, 14, & Justin Lim., 15, reports KABC.

The pair who played on the same water polo team were on a family trip when the mishap occurred in California.

One witness said he heard a loud boom when the tree limb snapped.

“I’m extremely sad and heartbroken to report that Dragon Kim and Justin Lee passed away over the weekend. The whole club sends their thoughts and prayers to the families of this tragedy,” the Northwood Water Polo Club posted on Facebook.
