Mark Stover
I remember being woken up early in the morning by a hellacious barking.
Peter Van Sant
It was 2009, three days before Halloween, a time when the boundaries between the living and the dead become blurred. Stephanie Poor said the dogs next door.
Mark Stover
Were going crazy and they were upset and it was loud.
Peter Van Sant
What'd you think to yourself when you were lying in bed listening to that?
Mark Stover
Something was going on over there and I wanted to get some more sleep and I was going to have words with Mark.
Peter Van Sant
Mark was Mark Stover, Stephanie's next door neighbor and her boss. Stephanie was a dog trainer at Mark's facility in Anacortes, Washington, an island community about 80 miles north of Seattle. He had built a successful business working with the dogs of the rich and famous and had earned the nickname the Dog Whisperer of the Pacific Northwest. That morning, Stephanie made her short commute to work. She assumed Mark had already left to meet a client in Seattle.
Mark Stover
And I'm on the phone leaving a message with him and he's in the driveway. The car is in the driveway parked up by the house. And I'm thinking, wow, that's weird because he really, he's probably going to be, you Know, a little antsy because he would have rather been gone by now.
Peter Van Sant
Mark had a reputation as a bit of a pit bull. Intimidating and impatient.
Mark Stover
I saw who I thought was Mark going into the house, coming out of the house, putting stuff in the back of the hatch.
Peter Van Sant
What made you think it was Mark?
Mark Stover
Because it was his hat and his jacket. He opened the door to the car, looked at the front windshield, grabbed something off the front and then just tore, like literally tore down the driveway.
Peter Van Sant
Then Stephanie went up to the house to the bathroom. As she walked up the driveway, she saw tire marks from the car and some spots of blood on the gravel. Stephanie assumed that the blood belonged to Ding, Mark's guard dog. Ding recently had surgery.
Mark Stover
I explained in a way that Ding must have ripped her stitches out.
Peter Van Sant
Out here, the blood wasn't the only sign something was wrong.
Mark Stover
I could smell the bleach before I even opened the door.
Peter Van Sant
Stephanie stepped inside. She noticed a bedroom door that was usually never shut was closed. And as she went into the house, Stephanie saw three big spots on the floor. Did they have a color?
Mark Stover
It was blood. It was red. Dark, dark red.
Peter Van Sant
Stephanie was worried. She kept calling Mark, but he never answered. Stephanie hoped the blood was from Ding's surgical wounds. She was doing her best to avoid imagining the worst. But the next morning when she came back to work, she was startled to see Ding sitting by the back door.
Mark Stover
She was on all fours and she was growling. Something had happened to her. Maybe she had had a stroke. It was obvious. One eye was in a horrible mess. We couldn't find Mark. I was calling him. I left a message. Mark, we're really concern. Where are you? You know, why is Ding here?
Peter Van Sant
An unsettling feeling hit Stephanie.
Mark Stover
I can only describe it as evil. Something horrible. Something terrible. I knew something bad had taken place.
Peter Van Sant
Stephanie called 91 1. Mark's new girlfriend had also called the police after not hearing from him. Soon after, sheriff's deputies arrived on scene. Investigators believed the bleach, the blood, and Mark's vanishing act all added up to one inescapable conclusion.
Mark Stover
It was a cold blooded murder.
Peter Van Sant
But detectives had no idea they were about to step into a hall of mirrors where nothing was as it seemed. I've never seen in my career a case that has as many twists and turns and mysteries as this case with Mark Stover. They soon discovered a story tangled in obsession.
Mark Stover
We don't have the truth yet. We have some of the truth, but we don't have all of it.
Peter Van Sant
But who was the hunter and who was the hunted? I'M Peter van Sant from 48 Hours. This is trained to kill the Dog Trainer, the Heiress and The Bodyguard Episode 1 Puppy Love the coastline of Washington State just north of Seattle is one of the most beautiful places on Earth. Back in the 1800s, my ancestors were homesteaders on an island not far from Anacortes, Washington. It's gone now, but one of my great greats even had a small apple orchard on Orcas Island. Anacortes is the gateway to the San Juan Islands, where ferry boats depart to these wooded jewels. I go hiking, swimming and fishing for Dungeness crabs and have always considered the small harbor towns here my gateway into tranquility and peace. That's why I was stunned when 48 Hours first got word about this murder. And then I learned that at the center of it all was a celebrity dog trainer.
Mark Stover
Mark was known as the dog whisperer of Anacortes and the dog trainer to the stars.
Peter Van Sant
That's Victoria Simmons, Mark Stover's younger sister. She said some of Mark's clients included Eddie Vedder from Pearl Jamie, longtime Starbucks CEO Howard Schultz, and Seattle Mariner Ichiro Suzuki.
Mark Stover
I believe he came to love all dogs. And no pedigree or fabulous pedigree. It didn't matter to him. He saw value in all of them and potential in all of them.
Peter Van Sant
Mark offered private training lessons. He could teach basic obedience, but his wealthiest clients wanted him to to train their pets to become protection dogs. This is audio from a video of Mark training a dog. He's standing in what looks like a gravel driveway, wearing a dark raincoat and his trademark brown hat with a round brim.
Mark Stover
Show me the motion again with the stick. Well, this is the barrage that I'm gonna do.
Peter Van Sant
A handler releases the dog. The dog sprints and bites hard enough to lock onto Mark's leg, which is covered in padding. And a tug of war ensues between the growling dog and Mark. Mark commands the dog to stand down. Right away, the dog lays on the ground looking straight ahead and awaits the next command.
Mark Stover
I just thought he was so incredibly interesting.
Peter Van Sant
His niece Julia, Victoria's daughter, said Mark sometimes expressed his love for dogs in eccentric ways.
Mark Stover
You know, he has this beautiful Porsche 911 and a BMW. And then he has this car called the dog a lack, the Cadillac. And I swear half the textile of the carpeting in that car was just dog hair that had woven itself into it.
Peter Van Sant
She said it smelled horrible. But one day they went for a.
Mark Stover
Drive, and instead of taking the Porsche or the BMW, he takes me and the Dog. And he said he didn't want his neighbors to know how rich he was.
Peter Van Sant
But Mark didn't start out rich at all. In fact, just the opposite. And his upbringing was far from easy.
Mark Stover
We went through. Our family went through a series of losses early in our childhood. Just seemed to be one after another.
Peter Van Sant
This is Victoria again, Mark's sister. They grew up in the Seattle area in the 1950s and 1960s.
Mark Stover
My father died when I was 6 months old, and Mark was 18 months old. Then shortly after that, a half brother was killed in a car wreck that was caused by my other half brother, which was sad. And then mother remarried, and shortly after she remarried, my sister died of pneumonia. She was nine.
Peter Van Sant
Their mother's second marriage also then fell apart.
Mark Stover
And so she remarried again. And he was an alcoholic. Life at home is tough.
Peter Van Sant
Mark struggled in school. According to Victoria, the family didn't know how to help him.
Mark Stover
He got kicked out of high school for smoking dope. I think he was 16. Yeah, he was on a bad path.
Peter Van Sant
And then their mother's third husband died of cancer.
Mark Stover
We were broke. Our family was broke. And there was a funeral and at the wake. And family friends brought a German shepherd puppy for a gift at Awake, which is such an odd choice.
Peter Van Sant
The German shepherd puppy was named Gunter. While maybe odd, the gift would be a godsend.
Mark Stover
I've never been able to talk to them and ask them what prompted them to do such an odd thing. But Mark and that dog bonded. That very day.
Peter Van Sant
Mark got in touch with the family's old vet. He encouraged Mark to join the Washington State search and rescue canine unit.
Mark Stover
They trained him and taught him how to train Gunter, and he loved it. He was flown all over the country to look for lost people as far as the Everglades. And it gave meaning to his life, gave purpose to his life. That dog saved him.
Peter Van Sant
Mark eventually started to train dogs in private sessions where he'd go to people's homes. In a News article from 1981, Mark is described as a disciple of the famous behavioral psychologist B.F. skinner. Skinner studied how rewards and punishment can condition behavior in humans. Mark applied that to dogs by training them with punishment and reward.
Mark Stover
He's told me that he was the first person to ever apply human psychology to dogs and to understanding the pack and how the pack works.
Peter Van Sant
Was your brother an innovator in the dog world?
Mark Stover
I believe he was.
Peter Van Sant
As for cats, Mark was once quoted saying that he didn't like cats because he wants something he can control. He added, dogs are easy to change. It's people that are hard to change. See, I can't put a choke chain around them.
Mark Stover
Foreign.

Peter Van Sant
Mark started training dogs in the 1970s and by the 1980s was a well established canine guru. Mark never married during that time. Then in the early 90s when Mark was nearing 40, a wealthy potential client called.
Linda Updike
I was looking to do some training with my dog and found him in the phone book.
Peter Van Sant
Linda Updike was the daughter of Wally Updike, one of the wealthiest businessmen in the state of Washington.
Linda Updike
I remember speaking with him on the phone and very I felt he was very arrogant, actually rubbed me the wrong way initially. Name dropped a lot of people and had quite a bit of an attitude. But yet he seemed also to know a fair amount about dogs. So I thought, let's try this out.
Peter Van Sant
Mark and Linda met regularly to train her dog. A bond was starting to form.
Linda Updike
I saw he definitely did have a connection with dogs and I felt that he would be able to help us.
Peter Van Sant
Mark definitely had a way with dogs and at times he could be charismatic with people.
Linda Updike
He was very bright and witty and charming.
Peter Van Sant
After eight or nine months, their relationship evolved. And even though Linda was 12 years younger than Mark, his sister says Linda was his type.
Mark Stover
She was tall, slender, beautiful. He seemed to like the girls from these wealthy families, which I always wondered about, just right down his alley.
Peter Van Sant
For one of their first dates, Mark asked her to go fishing.
Linda Updike
So I drove over and met him and did a day of fishing. And that began when we started dating shortly thereafter.
Peter Van Sant
So what was the attraction?
Linda Updike
You know, he was incredibly bright, eccentric, had A lot of similar interests that I did.
Peter Van Sant
Linda grew up camping, fishing and hunting. They connected over a love for nature and the open air. What started purely as business turned personal and they set out to build a relationship and a successful company at the same time. They were coming together despite being from two different worlds. While Mark's family had struggled, Linda Updike was the daughter of a millionaire.
Linda Updike
I grew up with my family doing a lot of camping on Whidbey Island. We have a small beach cabin up there. And I grew up so saltwater fishing, salmon fishing. I was born in California and then moved when I was very young to Bellevue, Washington. Went to junior high and high school there. Was very involved in horseback riding and competed doing grand prix jumping. And that was really my passion and where I spent my time in my youth.
Peter Van Sant
How good were you at this horse jumping?
Linda Updike
It probably depends on who you'd ask.
Peter Van Sant
And tell me also about your father. He's a famous man in the state of Washington. Very successful man in the state of Washington.
Linda Updike
Yes. He started with. Came from a very middle class background and went to University of Washington and then really became involved in a lot of different businesses. One of them being Chateau St. Michel, developing that.
Peter Van Sant
That's a very famous winery in Washington. Sold all over the world.
Linda Updike
Yes, it is. I'm very proud of his accomplishments that way. He was also involved in K2 Ski Company and JanSport Sporting Goods and different businesses throughout his career.
Peter Van Sant
Linda is her parents only daughter.
Linda Updike
She's a very good friend of mine at an adult age. Yes, we're mother daughter, but we're very good friends.
Peter Van Sant
That's Nancy Corbin, Linda's mother. She admits that she wasn't entirely thrilled when Mark and Linda started dating.
Mark Stover
Mark is not a choice I would have made for Linda. From the beginning, Mark showed an arrogance, had a where he wanted to isolate Linda. All bad signs. And so it was noticed by me right away.
Peter Van Sant
Nancy let her daughter make her own choices and was even supportive when Mark and Linda decided to go into business together. Linda said she had been interested in opening a dog boarding business. In 1992, Linda and Mark opened Island Dog Adventures. Linda ran the boarding part of the company and Mark handled the dog training. You essentially were the CEO, right?
Linda Updike
Yes, it was all of my. What we developed there was my business idea, my development, my money. I did capitalize it to go in.
Peter Van Sant
Linda thought Mark's reputation in the industry helped and her parents leased Linda the perfect place to set up shop.
Linda Updike
Beautiful piece of property that my family has owned. No longer owns, but did purchase in.
Peter Van Sant
The 80s, Kickit island and the surrounding area once belonged to the Swinomish tribe. Besides a clearing for some buildings, the island is a thick forest with tall Douglas firs and western red cedars.
Linda Updike
I don't think there's. There's probably many places like that. Whether dogs live on there or people live on there, it's just a terrific place.
Peter Van Sant
Their house was at the end of a long, narrow driveway that felt like you were almost entering Jurassic Park. The sprawling property, filled with wildflowers, hills and beaches, made it seem otherworldly. Business started booming. Over time, island dog adventures turned into a million dollar operation. Linda said that despite their success, Mark started to become obsessed with money, tightly controlling her spending.
Linda Updike
For example, an avocado that was too much money really upset him. I remember another time I was you.
Peter Van Sant
Guys have a million dollar business. He's upset that you bought an avocado.
Linda Updike
Yes. Yes.
Mark Stover
And you're serious?
Linda Updike
I'm absolutely serious, yes. He would be in a rage that I spent too much money and it was an inappropriate expenditure on things.
Peter Van Sant
Most of their attention was going to the business and not each other.
Linda Updike
And we were working, you know, seven days a week, 15 hour days, and there was really not any time for personal relationships.
Peter Van Sant
Despite her concerns, Linda was committed to making things work.
Linda Updike
I just kept thinking that if I could reduce our workload, if we could make some changes and try to get more personal time, that the relationship could be salvageable and work. So we went through some counseling and at that point in time, Mark did want to get married. And I, again because of the commitment, said, okay.

Mark Stover
They do, they do.
Peter Van Sant
And your brother thought this is the one. After all those years he married her and that this was going to be his partner for life.
Mark Stover
He adored this woman.
Peter Van Sant
But Mark seemed different to Linda after the wedding.
Linda Updike
Things were fine for about four months after the marriage and then it really started going south.
Peter Van Sant
What happened? What went wrong?
Linda Updike
I think my desires for a personal, truly a personal, loving marriage and relationship was something that he did not want to provide and could not provide.
Peter Van Sant
Linda wanted to move off the island, but she said Mark dug in his heels. He wanted to stay.
Linda Updike
Picket island meant a lot to Mark because it had quite a pretty prestige to it.
Peter Van Sant
Linda said she watched Mark's whole demeanor intensify.
Linda Updike
I saw him becoming more aggressive with people, for example, on the property that were trespassing, pulling guns on people and threatening them, being verbally aggressive and very threatening.
Peter Van Sant
According to Linda, Mark developed a reputation for threatening locals. He would even use his dogs to intimidate people.
Linda Updike
My experience with him was he was very unstable and with that and his agitated state, and he had real highs and lows and rages that he dealt with. It was very concerning to me and what his reaction would be to something, how that would affect my safety.
Peter Van Sant
After nearly 14 years together, including three years of marriage, Linda decided that she couldn't do this anymore.
Linda Updike
I recognized that I was so unhappy And I knew that I needed to leave the marriage and I got a separation.
Peter Van Sant
She moved out of their home. Linda left the island that was owned by by her family to start anew, set off on a new path alone. But she said Mark followed.
Linda Updike
He told me that he was listening to phone conversations and that he had been in my house and read my diaries and just, it was, it was horrifying. It was chilling to me every single moment. You're wondering when you walk out the door, is he going to be there? I know how he operated and his stalking abilities and hunting abilities.
Peter Van Sant
The fallout from their collapsed marriage started a nasty back and forth that would culminate in that bloody scene at Mark's house.
Mark Stover
This is war.
Peter Van Sant
This is goddamn war. You've worked my life enough.
Linda Updike
I really did feel that my life was in danger.
Peter Van Sant
Coming up on Trained to Kill, the Dog Trainer, the Heiress and the Bodyguard. I remember at that time thinking, this can't be real because no woman alone could go through this amount of harassment.
Linda Updike
My first thought was, oh, a body. I have a safe room in there. I have a plan A, a plan B, a plan C. I think Mark.
Mark Stover
Had a very real fear of what Linda was capable of doing to him. He told me that he was capable of killing without remorse.
Peter Van Sant
This is not a case of self defense. This is a case of cold blooded.
Mark Stover
Murder.

Title: 48 Hours – Episode: "Trained to Kill: The Dog Trainer, the Heiress and the Bodyguard"
In the gripping first episode of CBS News' 48 Hours, titled "Trained to Kill: The Dog Trainer, the Heiress and the Bodyguard," correspondent Peter Van Sant unravels the dark and complex story surrounding Mark Stover, a celebrated dog trainer known as the "Dog Whisperer of the Pacific Northwest." Stover's clientele included high-profile individuals such as musicians, athletes, and business magnates. However, beneath his esteemed professional facade lay a narrative of obsession, control, and ultimately, murder.
The story begins in 2009, just three days before Halloween, when Stephanie Poor, a dog trainer at Mark Stover's facility in Anacortes, Washington, experiences a disturbing morning. She is awakened by incessant barking emanating from Mark’s residence.
Mark Stover (00:28): "I could only describe it as evil. Something horrible. Something terrible. I knew something bad had taken place."
[05:34]
Stephanie notices unsettling signs: bloodstains on the gravel driveway and an aggressive demeanor in Ding, the family dog who had recently undergone surgery. Mark's sudden disappearance heightens suspicion, leading investigators to suspect foul play.
Peter Van Sant (06:13): "It was a cold blooded murder."
[06:13]
Mark Stover's journey into dog training began in the 1970s. By the 1980s, he had established himself as a leading canine behaviorist, applying principles from behavioral psychology to train dogs effectively. His innovative methods and charismatic presence attracted a wealthy clientele, earning him the moniker "Dog Whisperer of the Pacific Northwest."
Mark Stover (08:16): "Mark was known as the dog whisperer of Anacortes and the dog trainer to the stars."
[08:22]
Stover's ability to transform pets into protection animals made him a coveted trainer among celebrities and business elites alike.
In the early 1990s, Linda Updike, daughter of wealthy businessman Wally Updike, seeks Mark's expertise to train her dog. Initially put off by Mark's arrogance and attitude, Linda soon recognizes his deep connection with dogs and his professional prowess.
Linda Updike (16:05): "I was looking to do some training with my dog and found him in the phone book."
[16:05]
Their professional relationship blossoms into a personal one, culminating in their marriage on May 17, 2002, at the Four Seasons Hotel in Las Vegas.
Peter Van Sant (25:05): "On May 17, 2002, Mark and Linda were married in a small wedding at the Four Seasons Hotel in Las Vegas."
[25:05]
Together, they co-founded Island Dog Adventures in 1992, a business that rapidly grew into a million-dollar enterprise by blending Linda’s business acumen with Mark’s training expertise.
Despite the outward success, cracks begin to appear in Mark and Linda’s relationship. Mark's obsession with financial control becomes apparent as he scrutinizes every expenditure, no matter how trivial.
Linda Updike (22:22): "For example, an avocado that was too much money really upset him."
[22:22]
Their intense focus on the business leads to neglect of their personal relationship, resulting in long work hours and diminishing personal time. Efforts at counseling fail to bridge the growing divide. After nearly 14 years together, including three years of marriage, Linda decides to separate due to Mark's escalating aggressive and controlling behavior.
Following their separation, Mark's behavior becomes increasingly threatening. Linda recounts instances of Mark stalking her, invading her personal space, and exhibiting erratic aggression.
Linda Updike (28:24): "He told me that he was listening to phone conversations and that he had been in my house and read my diaries and just, it was, it was horrifying."
[28:24]
Her fears are compounded by Mark's volatile nature, making her feel endangered and leading to a violent confrontation that aligns with the alarming signs initially discovered by Stephanie Poor.
As law enforcement delves deeper into the case, they encounter a maze of twists and misleading clues that complicate the investigation. Mark Stover's enigmatic behavior and the intricate dynamics of his personal relationships present significant challenges in uncovering the truth.
Mark Stover (06:42): "We don't have the truth yet. We have some of the truth, but we don't have all of it."
[06:42]
Detectives are left questioning the true nature of Mark's actions and the extent of his involvement in the unfolding mysteries.
Mark Stover on Ding’s Behavior:
"I could only describe it as evil. Something horrible. Something terrible."
[05:34]
Linda Updike on Mark’s Controlling Nature:
"For example, an avocado that was too much money really upset him."
[22:22]
Mark Stover Reflecting on the Investigation:
"We don't have the truth yet. We have some of the truth, but we don't have all of it."
[06:42]
The episode sets the stage for an in-depth exploration of Mark Stover's life, his rise to prominence, and the dark turn his personal life took. As investigators continue to piece together the puzzle, viewers are left anticipating further revelations in subsequent episodes.
Peter Van Sant (29:10): "This is not a case of self defense. This is a case of cold blooded murder."
[29:10]
Produced by Sony Music Entertainment in collaboration with the 48 Hours production team, including executive producer Judy Tigard and senior producers Ryan Smith and Liza Finley, the episode showcases meticulous investigative journalism combined with compelling storytelling. Additional contributions from senior story editors, recording assistants, fact-checkers, and sound designers ensure a high-quality, engaging narrative.
For those intrigued by this initial episode, stay tuned to 48 Hours for ongoing coverage and deeper insights into the case of Mark Stover, the dog trainer whose life spiraled into darkness.
