In August, A&E aired a new documentary about the murder of Laci Peterson; the upcoming doc promises all new information about the case — including Scott Peterson’s first interview from death row in years. During the call with his sister-in-law Janey, Scott not only maintains his innocence, but also describes the moment he found out he was convicted of murdering his wife and unborn child.

EXCLUSIVE: Scott Peterson Describes Life With Laci in Chilling Prison Letters

“It was just like this amazing, horrible, physical reaction that I had,” he says of hearing he was convicted of first- and second-degree murder. “I couldn’t feel my feet on the floor. I couldn’t feel the chair I was sitting in. My vision was even a little blurry. And I just had this weird sensation that I was falling forward — and forward and down and there was going to be no end to this falling forward and down, like there was no floor to land on. I, I was staggered by it. I had no idea it was coming.”

In 2012, a lawyer for Scott — who is slated for execution for by 2021 — filed an appeal, arguing that not only was the jury was influenced by the incessant media coverage of the case, but also that there was insufficient evidence to find his client guilty. Check out all the evidence found against Scott Peterson — and decide for yourself whether he’s guilty of killing his wife and unborn child.

Scent-sniffing dogs picked up Laci’s scent

One of the most contentious pieces of evidence came courtesy of dogs who were trained to pick up the scent of Laci; a handler for one of the dogs says that the pup picked up a scent of Laci in the Berkley Marina, where Scott claimed he was fishing on the day of his wife’s disappearance. The dog’s handler said the dog reacted to the scent at the marina just four days after Laci’s disappearance, and the body of Laci and her unborn son were discovered north of the Marina months later in April of 2003.

Scott’s defense attorney claimed that the dog’s evidence was unreliable, comparing it to “voodoo,” “nonsense,” and likening the exercise to “pin the tail on the donkey.” When Scott’s team filed an appeal in 2012, they argued the dog-sniffing evidence was “unreliable” saying the dogs failed two-thirds of tests under similar conditions.

Laci’s hair was found on the boat

During the trial, many were critical that the trial lacked a significant amount of forensic evidence; in fact, one of the only pieces of forensic evidence found against Scott was a single hair, believed to be Laci’s, which was found on pliers kept on Scott’s boat. During the trial, the prosecution argued that, while alive, Laci had never seen Scott’s boat — and suggested that the reason her hair was on the boat is because Scott had her body on the boat after killing her.

Planter pots found in the marina matched those in a storage unit in Scott’s name

According to FBI agent Robert Chachon, who worked on the case, there were planter pots found by divers in the marina that many believed were used to weigh down Laci’s body that matched broken pots that were discovered in a storage unit registered to a storage unit in Scott’s name.
