The names of five family members killed and a sixth injured in a rock slide Monday on the Agnes Vaille Falls trail in Chaffee County were released Tuesday by the Chaffee County Sheriff's Office.

In a news release, spokeswoman Laura Smith stated the identities of the five hikers had not been confirmed by the Chaffee County coroner, but reliable sources said the victims were Dwayne Johnson, 46, and Dawna Johnson, 45, their daughter Kiowa-Rain Johnson, 18, and their nephews Baigen Walker, 10, and Paris Walkup, 22. The nephews were visiting from Birch Tree, Mo.

Gracie Johnson, 13, Dwayne and Dawna Johnson's younger daughter, was identified by Chaffee County spokeswoman Monica Broaddus as the sole survivor.

The girl was pulled from the debris by first responders shortly after the rock slide and flown to Colorado Children's Hospital in Aurora.

Gracie Johnson was listed in stable condition following surgery for a severely broken leg and remained hospitalized, according to Smith's news release.

Dwayne and Dawna Johnson were both coaches at Buena Vista schools and their family was well-known within the community for being active in local school and community events, the news release stated.

The area surrounding the rock slide was reportedly very unstable, slowing recovery efforts by numerous local agencies. The debris included very large boulders that could not be moved without proper equipment.
