Its fears grow that missing teen Tiley might be buried there.

Tiley visited the park with her brother, J J, and their mom, Lori Day Bell, last September 8th.

Court papers show that police have located two photos of Tiley taken in the park that day.

We have found no witnesses who can verify they have seen Tiley since the court documents quote one detective on the case.

Now, police are reportedly waiting for the snow and Yellowstone to melt.

They consider mounting a search for a body.

It's a daunting task.

The park covers more than 3000 square miles, nearly three times the size of Rhode Island.

It could be like trying to find a needle in a haystack.

At this point, they can't do any digging or any intense searching because there is so much snow and the ground is frozen.

Tyler's brother, J J.

Is also missing.

This is believed to be the last known video of him taken from a ring doorbell camera in Idaho September 17th 9 days after the trip to Yellowstone, just days after the ring video.

J.

J also disappeared.

Laurie Day Bell has been charged with child abandonment.

She's in jail in Hawaii, fighting extradition to Idaho.

Lori remains locked up in Kawai on $5 million bail.

Thank you, Laurie.

Day.

Belle has denied any wrongdoing, all right.
