Tex McIver

Two days after Diane's death, Tex and his then-lawyer met with Atlanta Police Department homicide detectives.

The question is why.

Reporter Bill Rankin's Breakdown podcast takes a deep dive into the Shakespearean drama surrounding Tex McIver.

He's a 48-hours consultant on the case.

Using a similar car, Rankin showed us how the bullet that killed Diane McIver traveled through the passenger seat of Texas' SUV.

It hits there.

And exits out here.

The bullet went through Diane's left rib cage and diaphragm, severed a vein and artery in her spleen, and then hit several organs, including her left kidney and stomach.

That night, detectives were anxious to hear Danny Joe Carter, the car's driver, explain what Tex did after he shot his wife.

And he said, no, Emory's closer.

There were four hospitals, all approximately less than five miles from where the shooting is believed to have taken place.

Emory was the farthest, at about 4.3 miles.

But one of the best trauma centers in all of Georgia, Grady, was only about 3.2 miles away.

Family friend Sheriff Howard Sills, who is not involved in the case, says no way and explains that Grady just was not on Texas radar.

This dramatic surveillance footage shows the SUV arriving at Emery's emergency room and Tex helping Diane into a wheelchair.

Then, before surgery, Diane made a critical statement to her doctors.

Her husband did not mean to shoot her.

But two hours later, Diane McIver died on the operating table at 12.49 a.m.

Now it was up to detectives to determine, was it truly an accident or was it cold-blooded murder?

This Smith & Wesson .38 caliber revolver that killed Diane was in the car's center console, inside a plastic bag, when it was handed to Tex by Diane.
