Lester Holt

This is not justice.

It is vengeance.

Mrs. Adelson, control yourself.

With brand new evidence.

She actually called me her jail daughter.

All the explosive testimony, including the prosecution's newest star witness.

But first, we have to roll back the years to the summer of 2014 in sunny Tallahassee, Florida.

The opening scene of what I've come to think of as a Shakespearean-like drama.

A tale of bitter divorce, dueling grandparents, twisted family ties, and the custody of two little boys that all started with one tragic and mysterious murder.

It's right next door to my house.

11 a.m.

on July 18th, a man heard gunshots from a neighboring garage and quickly called 911.

He's inside, the car is running, and he's got blood all over his head.

He was Dan Markell, a beloved and accomplished law professor at Florida State University.

Markell had just arrived home from the gym when he was shot twice in the head.

His car window smashed, his eyeglasses broken, his assailants apparently pulling away.

The car was backing up.

It was light colored, white or silver.

I want to say it was a Prius.

When Dan's friends, Jared and Heather Ross, first heard about a shooting in town, they couldn't believe it.
