Detective Chevalier

It was one of the most brutal scenes that I've been to in 32 years law enforcement.

You could see the rage.

Within an hour of getting to the crime scene, we knew that we needed to look for Andrew Beard.

Andrew Beard is the suspect?

At first, this seemed like an open and shut case.

But as it turned out, Andrew Beard was only half the story.

Tonight's 48 Hours will continue.

Once we talked to Alyssa's mom, we had an idea who we were looking for.

And who was that person?

That person was Andrew Beard.

So this is the device that was put on her car.

That was all part of his plan to catch her doing something that he believed that she shouldn't be doing to gain an advantage in that child custody dispute.

So this is one of the makeup vials that were recovered from inside one of the bags in the F-150.

It's really dark.

Was to disguise Andrew Beard's face to make him look like an African-American.

He drove it to that location and he fled back to his house the morning of the murder.

He is doing the Bigfoot run from this vehicle.

We were able to recover multiple spots where blood was recovered.

That was later tested to be Alyssa's blood.

He purchased a Halloween costume.
