CHEYENNE, Wyo. (AP) — The family of Colorado Sen. Mark Udall says searchers looking for his brother in western Wyoming's Wind River Range have found his body.

James "Randy" Udall had left June 20 for a week-long solo backpacking trip and was due back a week ago.

Sen. Mark Udall's office released a statement from the family Wednesday night saying the 61-year-old's body had been found. The family says that while an autopsy is forthcoming, it appears he died of natural causes.

The family says he died doing what he loved most: hiking his favorite mountain range in the world.

He had indicated to his wife he planned to head for the scenic Titcomb Basin. His family says it appears he was on the obscure, off-trail route that he had proposed to his family.
