In fact, Ajay was scheduled to compete in a 100-mile run the week after he went missing.

So responders have a hard time wrapping their heads around the scale of the search.

This is Randy Meggardly.

He was a patrol deputy for the Sheriff's Department and one of Ajay's running buddies.

He reiterates to the command post that Ajay was a beast.

What do you mean by that?

Goat trails?

Wow.

And so part of the activity was figuring out how to get to the end of it.

Yeah, in one piece.

Hearing Megardly talk about ultramarathoners, it sounds like they have no off switch.

So maybe Ajay just overdid it.

That's a theory, that Ajay was doing the Forrest Gump and just kept running and got himself into a tailspin of dehydration.

Responders take note and fan out across the search grid.

Ranger Jack Farley again.

But it doesn't take long for the pros to realize they're in over their heads.

So Farley leads a few groups of deputies and bloodhounds down the local trails.

The dogs pick up a scent, possibly Ajay's, on a trail that's near a local resident.

That guy reported to searchers that he heard a single gunshot at sunset the day Ajay vanished.

It's a detail the sheriff's department registers as a potential clue.
