Portland, Ore. • The 21-year-old daughter of one of men in the Utah-based music group The Piano Guys has been reported missing and may have gotten injured or lost on a hike in the Columbia River Gorge in Oregon, authorities say.

Anna Schmidt, the daughter of The Piano Guys' Jon Schmidt, was last seen Sunday, Portland police Sgt. Pete Simpson said. She was reported missing Wednesday, and her car was found a day later near Bonneville Dam.

Schmidt enjoys hiking and she recently bought a new tent and backpack. Crews were searching the area surrounding the Toothrock Trailhead on Friday.

Her mother, Michelle Schmidt of Salt Lake City, told KOIN-TV that she arrived in Portland this week to go on a camping trip with her daughter. After flying in, she learned her daughter hadn't been seen since Sunday.

Anna moved to Portland from Salt Lake City in July. She is 5-foot-4, 125 pounds and has brown hair and brown eyes. Anyone who may have seen her is asked to call 911.

Jon Schmidt joined his wife in Oregon, and both were at the search command post Friday.

"If anyone was up here hiking Sunday afternoon, please take a look at the picture. If you know anyone who was hiking here, have them take a look at her picture, see if you recognize her," Jon Schmidt said.
