PINEDALE, Wyo.-Randy Udall, the 61-year-old brother of Sen. Mark Udall (D-Colorado), has gone missing in Wyoming after setting off for a backpacking trip on the Wind River Mountains.
"Mark is concerned about his brother's whereabouts and he continues to closely monitor the situation," said Sen. Udall's press secretary James Owens. "He and his family hope for the best."
The mountains are located about 80 miles southeast of Grand Teton National Park. Randy Udall, an avid backpacker, was hiking alone.
He was supposed to exit last Wednesday, but never checked in with his family.
The Sublette County Sheriff's Office is working with search and rescue officials to search a 225 square mile area.
Jim Mitchell, the Emergency Management Coordinator for Sublette County says there are currently 29 people from multiple agencies actively searching for Randy Udall.
"There are few new leads since the search began on Friday," Mitchell said.
The search is a coordinated effort using ground crews and a helicopter to conduct aerial sweeps.
Randy Udall, who lives in Carbondale, Colorado, is familiar with the area.
Search and rescue officials say he has hiked the Wind River Mountains many times over the past thirty years.
