How Did Kathleen Peterson Die? Watch an Exclusive Clip from An American Murder Mystery: The Staircase

Michael Peterson was living the American dream: With a successful writing career, a beautiful family, and a picturesque home in Durham, North Carolina, he and his wife Kathleen seemed to have it all … then everything changed.

In the early morning hours of December 9, 2001, Michael called 911 to report that his wife was unconscious and lying in a pool of blood after possibly falling down "15, 20, I don't know” stairs in their home. Michael claimed it was a tragic accident and said that his wife had been drinking and taken some Valium. But the police, and armchair detectives around the world, had other ideas—namely, that Michael was to blame.

For nearly 20 years, the mystery surrounding Kathleen Peterson’s death has only grown, especially in the wake of Michael’s trial—where he was found guilty, but later managed to walk free—and the number of sometimes-odd theories that have sprung up to explain what happened (including the idea that she was attacked by an owl).

The case has been featured on a number of true crime series, including Dateline and Forensic Files, and spawned a 2004 docuseries, The Staircase, directed by Oscar-winning filmmaker Jean-Xavier de Lestrade. Now, Investigation Discovery is going back to the scene of the crime for a three-part series, An American Murder Mystery: The Staircase, which will premiere on Sunday, April 8 at 10/9c.

“The death of Kathleen Peterson is one of the most confounding cases in history,” Henry Schleiff, group president of Investigation Discovery, American Heroes Channel, and Destination America, said in a press release. “There are so many pieces to this puzzle—from Michael’s salacious secrets to investigator misconduct to the odd owl theory—so, we are eager to bring our viewers the first complete look at this fascinating crime and subsequent trial.”

Another theory? The “blow poke” theory, which Kathleen’s sister Candace explains in this exclusive clip below.

Getting a full eight hours of sleep can be tough these days. If you’re having trouble catching enough Zzzs, consider giving these highly rated and recommended products a try.

1. Everlasting Comfort Pure Memory Foam Knee Pillow; $25

For side sleepers, keeping the spine, hips, and legs aligned is key to a good night’s rest—and a pain-free morning after. Everlasting Comfort’s memory foam knee pillow is ergonomically designed to fit between the knees or thighs to ensure proper alignment. One simple but game-changing feature is the removable strap, which you can fasten around one leg; this keeps the pillow in place even as you roll at night, meaning you don’t have to wake up to adjust it (or pick it up from your floor). Reviewers call the pillow “life-changing” and “the best knee pillow I’ve found.” Plus, it comes with two pairs of ear plugs.

White noise machines: They’re not just for babies! This Letsfit model—which is rated 4.7 out of five with nearly 3500 reviews—has 14 potential sleep soundtracks, including three white noise tracks, to better block out everything from sirens to birds that chirp enthusiastically at dawn (although there’s also a birds track, if that’s your thing). It also has a timer function and a night light.

3. ECLIPSE Blackout Curtains; $16

According to the National Sleep Foundation, too much light in a room when you’re trying to snooze is a recipe for sleep disaster. These understated polyester curtains from ECLIPSE block 99 percent of light and reduce noise—plus, they’ll help you save on energy costs. "Our neighbor leaves their backyard light on all night with what I can only guess is the same kind of bulb they use on a train headlight. It shines across their yard, through ours, straight at our bedroom window," one Amazon reviewer who purchased the curtains in black wrote. "These drapes block the light completely."

You can choose between seven different colors and several natural sounds as well as a regular alarm beep, but why would you ever use that? “Since getting this clock my sleep has been much better,” one reviewer reported. “I wake up not feeling tired but refreshed.”

Though the science is still out on weighted blankets, some people swear by them. Wirecutter named this Baloo blanket the best, not in small part because, unlike many weighted blankets, it’s machine-washable and -dryable. It’s currently available in 12-pound ($149) twin size and 20-pound ($169) queen size. It’s rated 4.7 out of five stars on Amazon, with one reviewer reporting that “when it's spread out over you it just feels like a comfy, snuggly hug for your whole body … I've found it super relaxing for falling asleep the last few nights, and it looks nice on the end of the bed, too.”

10. Philips Smartsleep Snoring Relief Band; $200

Few things can disturb your slumber—and that of the ones you love—like loudly sawing logs. Philips’s Smartsleep Snoring Relief Band is designed for people who snore when they’re sleeping on their backs, and according to the company, 86 percent of people who used the band reported reduced snoring after a month. The device wraps around the torso and is equipped with a sensor that delivers vibrations if it detects you moving to sleep on your back; those vibrations stop when you roll onto your side. The next day, you can see how many hours you spent in bed, how many of those hours you spent on your back, and your response rate to the vibrations. The sensor has an algorithm that notes your response rate and tweaks the intensity of vibrations based on that. “This device works exactly as advertised,” one Amazon reviewer wrote. “I’d say it’s perfect.”
