Detective Carter

We started investigating Miles Bryant's past and there starts to be a bunch of weird behavior with women.

We began to realize who Mr. Bryant really was under the surface.

And it was this repeated pattern, all involving young women.

I was very scared for my life.

The funeral was very surprising seeing a lot of community together.

A lot of people out there supporting our family.

Susana Morales' family got a call from investigators just hours after laying her to rest Monday.

22-year-old Miles Bryant started the day as an officer with Doraville Police.

Now he's behind bars, off the job, and linked to the disappearance of a dead teen.

I got search warrants and conducted forensic downloads on his cell phones and then began reviewing that data.

I was able to show and put him out there based on his activity logs on his cell phone.

Like, how quickly are you moving your steps and stuff like that?

At 1.20 a.m., he traveled 381 meters, 131, 140 meters, 141, 373 meters.

Technology is amazing.

In a cell phone, you can see how many steps somebody takes.

You can see their heart rates, get their location.

Do you know where she was found?

So when Miles told us, he was just sitting in the truck.

Do you ever go in the woods and stuff out there?

In the woods?
