Several weeks after the daughter of The Piano Guys co-founder Jon Schmidt was reported missing in Oregon, the dead body of Annie Schmidt was found at the bottom of a cliff, authorities confirm to PEOPLE.

She died of blunt force head injuries, the Multnomah County Medical Examiner’s office tells PEOPLE, adding that her death has been ruled accidental.

On Saturday, Jon Schmidt posted to the Facebook group Find Annie Schmidt, announcing a medical examiner told them Annie’s remains were found below Munra Point.

Annie, a nickname for Anna, was last seen by her roommate on Oct. 16, when she went hiking in the Tooth Rock Trailhead area of Oregon. Her father told FOX12 Oregon that she sent him a Snapchat message that day indicating she was going on a hike.

She then went missing, prompting Schmidt to ask the public for help in finding her.

Schmidt thanked those who offered the family support during the period Annie was missing.

“There is no way to thank our Heavenly Father and His Son Jesus Christ for the support we have felt through you,” Schimdt wrote on Facebook. “You have searched with us, prayed with us, hoped with us, fasted with us, supported us and sacrificed for us. We thank you from the very bottom of our hearts!!!!”

Schmidt is part of the Utah-based musical group The Piano Guys. They posted their first YouTube video in 2010 and have racked up more than a billion views of their videos since. They have also scored four No. 1 classical music albums. Schmidt is one of the co-founders.
