The most shocking thing that I learned for the doctor's testimony was that not a single fatal blow was delivered from the skillet.

From NBI Studios, this is Truth Injustice, a crowdsourced investigation in real time. I'm Bob Ra.

The Courtney's double homicide crime scene is by far the most perplexing that I've ever dealt with.

The choice of weapons, the forensic countermeasures, staging, the note, they all continue to erect barriers to the truth.

As of right now, we at least have a clear idea of what the crime scene looked like after the killer or killer's fled the scene.

But today, we're going to try to get a little bit closer to figuring out what happened during the actual assault.

Lloyd and Agnes Courtney suffered 75 injuries during the attack that resulted in their deaths.

Dr. Nizam Pierwani performed their autopsy, and through his trial testimony, he shares his opinions on what exactly happened during the murders.

With all of the chaos in this very complicated crime scene, what actually killed Lloyd and Agnes Courtney?

Let's dig into Dr. Pierwani's testimony and see if we can't find that answer.

Direct examination begins with prosecutor Alana Minton questioning Dr. Pierwani about his qualifications.

Perwani graduated from medical school in 1976. He then moved on to post-grad training and pathology at Baylor Hospital for four years.

At the time of the trial, he was a board-certified pathologist with certification in anatomic clinical and forensic pathology, and he had been serving as the Tarant County Medical Examiner for over 30 years.

He estimates in his testimony that he has performed over 5,000 autopsy throughout his career.

Dr. Pierwani performed the autopsy on Lloyd and Agnes on the morning after their murders.

He began Lloyd's autopsy at 9.30 in the morning, and then Agnes's at 12.30.

Lloyd's body was described as fully clothed when he received it, and he was covered with, quote, large amounts of blood.

As his clothes were removed, Dr. Pierwani notes that Lloyd has sustained several injuries, including cut wounds, stab wounds, and blunt-forced traumatic injuries.

He testifies that he documented the presence of, quote, at least seven cut wounds and 15 stab wounds.

The blunt-forced wounds were a little more complicated. Pierwani testified that, quote,

they were very complex injuries and they were pattern injuries, but all in all, there were at least 17 blunt-forced traumatic injuries noted on the body's surface.

He begins to get into the details of the blunt-forced injuries, but much like we saw in Patrick Gas's testimony last week,
