[gentle music] Sheriff Wheatley says the Shearer family's efforts are impressive.

They are out spreading the word.

You know, they're inspired not only with their hope to find their, their loved one, but they are big advocates of missing persons, not only just their family, but worldwide.

Even Sheriff Wheatley had gotten his hopes up.

I think we all had high hopes and expectations, as much as we know in this job not to do that.

We followed everything we had to lead us to that, to that area.

We did a thorough search.

You know, these dogs obviously can't tell us it was Cheryl.
