Original story:

A teenager remains missing nearly three weeks after he left a youth facility in Gallatin.

The family of Dylan Regenold created a Facebook page after the teenager went missing and there have been thousands of shares with information looking for help finding him.

Regenold was staying at the Volunteer Youth Academy in Gallatin when police say he pried a window open and used his bed sheet to escape from the second floor.

He was last seen wearing jeans and a long-sleeved shirt.

According to his family, no one has heard from him since. He had no phone, money, car or anyone with him.

One of the posts read: "The crushing weight of the unknown and the reality that either my son has left this earth or someone is helping him and refusing to come forward has become almost too much to bare."

Anyone with any information should call the Gallatin Police Department at 615-452-1313.
