Murder On Lockhart Road

Bizarre Twists And Evidence Keep Turning Case On Its Head

(CBS)  While Kim and Jill had been shot in the head, Brad had been shot in the chest and Dr. Corey says the little boy bled to death internally. Before he died, Corey says Brad would have been able to hear, see and speak. And she believes the pattern of his injuries shows Bradley was likely face-to-face with his killer.

On Camm's T-shirt, investigators found eight tiny blood drops, which prosecutors claim got there when he pulled the trigger.

Investigators hoped blood stain expert Rod Englert could connect the dots. Using stage blood and a piece of paper, Englert shot a blank at the blood, demonstrating how it would splatter.

"You cannot create that pattern. This is very indicative of high velocity mist," explains Englert, who was hired by the prosecution.

Englert examined Camm’s shirt and identified the stains as what’s called "high velocity impact spatter," caused by a bullet hitting a body. But that’s just one theory. The defense says those drops of blood actually back up Camm's version of what he did when he discovered the bodies.

"I grabbed Brad, picked him up," Camm explains. "I was gonna try to do CPR on him."

Bart Epstein, a blood stain expert for more than 30 years, was hired by the defense and believes those eight droplets on David’s shirt got there when he leaned over to remove his son's body from the SUV.

Epstein says those tiny drops of blood were made when Camm‘s shirt brushed against the tips of Jill’s bloody hair. Using a wig and some stage blood, Epstein demonstrated how these blood stains could have gotten on the shirt.

He believes these stains can look like high velocity impact spatter to some people. But in this case, the number of blood stains could be as important as their size.

"Gunshot will produce hundreds of stains coming back. I’ve never seen, I believe the other experts for both the prosecution and the defense have indicated that they’ve never seen just seven small or eight small stains from a gunshot. I’ve never seen that," says Epstein.

Camm’s lawyers believe if he had pulled the trigger at point blank range, his clothes would have been covered in blood.

After roughly two months of arguments and testimony, the jury finally got the case. On a Sunday night, three days after they began deliberating, jurors reached a verdict: guilty.

Jurors believed Camm molested his daughter and murdered his family at least partly to cover that up. They believed the forensic evidence more than the 11 men at the gym, who said they were with Camm the night of the murders.

He was sentenced to 195 years in prison.

Kim's father Frank Renn says he felt relieved by the verdict, but not better. "I think he did it. I want him behind bars. I guess it makes me feel comfortable that he’s behind bars," Kim's mother Janice added.

The Renns thought Camm would be in prison for the rest of his life, but this story turned out to be far from over: a new defense attorney was determined to uncover the truth about some old evidence, including the grey sweatshirt.
