I did, the driver said.

Now they could find and speak to the three individuals who may have been the last people to have seen Dr. Schwartz alive.

The dude they were hot on now, the driver of that car, lived two hours away from the Schwartz house.

Why in the hell was he so far away from home, in the driveway of a man who was murdered on that night?

And...

Why hadn't he gone to the Schwartz house and asked to use his phone?

Why walk in the rain and mud a half mile away when all you had to do was track 50 yards down a driveway?

Locke stayed behind while DiBenedetto headed out to Prince William to conduct surveillance on the house where the car was registered.

Turns out the Loudoun County Sheriff's Office also put out a bolo.

Be on the lookout for the plate number of the vehicle stuck in the mud.

Although they now had two of the three in custody, that third person along for the ride that night was still alive.

A mystery.

Detective Greg Locke rushed to Prince William County to question both persons of interest.

See what, if anything, they knew and could remember from that night, or if they had seen anything out of the ordinary.

He also wanted the name of the third person with them.

The kid they now knew had sat with Schwartz's neighbor and actually drank hot tea and ate biscuits with them while waiting for the tow truck.

They had shown the neighbor a photo of the one kid they had in custody, and the neighbor indicated it wasn't the same person he had met.

Katie Inglis and Mike Fole were actually dating.

Locke and his fellow investigators discussed the idea that perhaps they proceed with caution just in case the kids were involved.

They also needed a warrant before they could go into Mike's home and poke around.
