Not a lot of people get into West Point, but that was part of Delbert.

He was a pathological liar.

So was Delbert just the brawn while Allison was the brains?

Even though there was no hard evidence linking Allison to the crime, that was Jessica's theory.

I felt like she was the one that came up with the idea to set this fire and for him to get to work so that he'd have an alibi.

Do you think Allison played a role in your mom's murder?

Yeah.

And there was something else in the case file that pointed to Allison, something her cousin by marriage, Sherry, had said back in 2005.

Sherry had some pretty damning statements to make about Allison that she says Delbert told her.

This is the first person really to bring Allison into this in a big way.

But Prosecutor Shepard knew that part of Sherry's story about Delbert couldn't be used in court.

It would be hearsay and inadmissible.

Allison was never charged with anything relating to the fire.

Delbert Mills went on trial in January of 2013, waiving his right to a jury in favor of a bench trial.

After just three days of testimony, the judge gave his verdict.

Guilty?

What was his reaction to that in the courtroom?

Delbert was sentenced to life in prison.

Sometimes it takes a while.

It got done.
