How far that person had gone to throw investigators off the trail wasn't clear until a few days later, when detectives got a call they never could have expected.

I'm a religious person.

Things happen for a reason that you, you don't, sometimes it's better that you don't ask questions of why it happened, right? Um, as I was sitting at the Gallatin County Sheriff's Office, we were doing some work on it, um, one of the deputies walks in and says, "Hey, we just responded to a complaint on Moose Creek." So we got a call from a citizen that said he was a friend of Dustin's and that he had a dream the night before about water.

And that he and his girlfriend drove from outside of the Bozeman area, uh, to Moose Creek, and they drove up the road, and they got out of their vehicle versus right next to the creek and walked out and found two cell phones.

One of them I think was hanging in a tree.

I can't tell you the number of law enforcement that went up and down that road, and this guy has a dream, and he finds these two cell phones.

Derek's colleagues discovered that Dustin's phone had remained still all day Friday, but had started moving again later that night, nearly 24 hours after Dustin was killed.

We got a piece of butcher paper out.
