Tom Henderson

There was a lot that didn't add up for Henderson and the rest of the prosecution team of Danielle McCollum and Karen Cook.

Then there was the location.

Tina's body and truck were actually found in a suburb of Memphis on a safe residential street in the town of Bartlett.

So you would expect law enforcement to be suspicious, but not Gary Hathaway, Joe's friend and alibi, who was about to make a disturbing discovery.

It was time for friends and family to not just mourn the passing of Tina Corona, but to come together and celebrate her life.

But some people thought the tone of the service was wrong, and that Joe's behavior in particular was inappropriate.

Gary started having serious reservations about Joe as soon as Tina's body was found in the back of her truck on a quiet, dead-end street in a Memphis suburb.

And in relationship to this, where is the storage unit?

Gary was at the Coronas house on Monday when police broke the news about Tina.

The coincidence about where the truck was found was still bothering him when he noticed there was one car too many parked at the house.

So this gets a little complicated.

This is a model that is not to scale, but it will help illustrate that in 2008, the Coronas had eight cars, four that they kept at the house and another four that Joe kept six miles away here at the storage unit.

So the fact that the red Corvette and the red Chevelle were both at the Corona house that Monday was a big problem.

Why is the red Chevelle being in the garage such a big deal for you?

What, why is it so telling for you?

With four cars at the house and three cars at the storage unit, the question becomes, which car did Joe drive to the storage unit and leave behind in order to get the Chevelle back to the house?

Gary realized the only car missing was the Avalanche, parked a half mile away from the storage unit.

And the Avalanche has just been found several streets over with the body of his dead wife.

Is that the moment that you said,

Gary kept his suspicions to himself until he and his wife, Pat, finally had a moment alone.
