Jason McDermott

Mickey, who had taken classes in criminology, knew what that meant.

That afternoon, Mickey cut off all communication with Jason.

For detectives, one giant obstacle remained.

An alibi that has gotten thousands of suspects off the hook ever since the digital age began.

In modern criminal investigations, your phone's location is nearly always assumed to be where you are.

And Jason's phone was definitely at his apartment at the time of the murder.

Okay, so what about Jason's car?

Investigators scrolled frame by frame through hours of video.

And then, there it was.

We did see a vehicle that we believed was Jason McDermott's vehicle.

Same kind of vehicle, same color?

Correct.

On the cameras, you can see a bent-up front license plate.

You can also see two objects.

On his dash and hanging from his mirror.

And those are consistent with Jason's car?

They are.

And it's the right time.

It's exactly the right time that puts someone there at the time of Morgan's murder.

For prosecutors, it told a story.
