This defendant's decision to what would benefit her in the short term took the life of a brilliant

father of two little boys and caused a lifetime of loss for his loved ones.

Today's episode starts in Tallahassee, Florida on July 18, 2014, just before 11am.

Jan Mark Hell, a Florida State University law professor, is sitting in his car in his driveway.

He has just returned home from first dropping his kids off at preschool and then going to a class at the gym.

He's on the phone with someone, discussing a potential new school for one of his two young sons.

We'll never know if he ever realized he had been followed that morning.

And when he pulled into his driveway that morning after his workout, the killer's pulled in right behind him.

We'll never know if he saw the gunman, who we now know was Sigfredo Garcia, approach his driver's side window,

or if he just happened to look up and there he was.

Seconds later he is shot in the head, twice.

And Sigfredo Garcia runs back to a light-colored Toyota Prius he had rented a couple days prior,

hops in the car and heads back to his hometown of Miami, his friend Louis Rivera by his side.

Dan Mark Hell dies 14 hours later while in a hospital bed.

What I just told you is what has been accepted as fact in a courtroom.

In fact, I first covered this case on Court Junkey in episode 93, which was divided up into two parts.

Listening to those episodes are not required to understand today's, but there will be additional details there that I'm not going to repeat in this one.

In episode 93, Sigfredo Garcia went to trial and was convicted of the murder.

His friend and co-defendant, Louis Rivera, had turned on him, pleading guilty and cooperating with the state of Florida.

At that trial, Sigfredo wasn't the only defendant seated at the defense table.

His on-again, off-again girlfriend, sometimes they referred to each other as husband and wife.

And children's mother, Catherine Katie Megbanova was there too.
