Barnes had a tattoo across his abdomen of a Navajo and Central Indian American rain cross associated with Riverside. His Facebook page lists Riverside as his hometown, and Seattle as his current city of residence.

Search teams discovered Barnes’ body inside the Mt. Rainier park, which is located in southwest Washington State.

“The body was located in a river,” said Ed Troyer of the Pierce County Sheriff’s Department. “[Searchers] had to walk in the river, and they have located the body.”

Mount Rainier Park Ranger Chuck Young said the cause of death was not yet known. “Investigators are now working on figuring out how he died,” said Young.

Authorities say Barnes shot and killed park ranger Margaret Anderson in the early hours of Sunday morning when she attempted to prevent him from entering the park.
