Maryland murderer who believed cellmate was Jesus, has ‘an aura of evil’

Lou Luciano faced “pure evil” and hopes he'll never do it again.

“My job has taken me to North Africa, East Africa, Iraq, Afghanistan, just about every place you can imagine,” the retired FBI special agent told Fox News Digital. “I've dealt with some of the most evil people on the planet, but this guy is the worst. He's a heretic of the human race. He doesn't belong here.”

“It's like sitting with the devil,” Luciano added.

Maryland serial killer Hadden Clark is the subject of Investigation Discovery's (ID) new documentary series Born Evil: The Serial Killer and the Savior, directed by Michael Bay. The series follows how the 72-year-old Clark made a shocking confession to his cellmate, Jack Truitt, who believed he was Jesus Christ, and leads investigators to solve cold cases linked to Clark.

The book features new interviews with Truitt, Clark's brother, Jeff Clark, the victims' families and others closely connected to the case.

Luciano, who worked on the case in the 1990s and spoke in the documentary series, vividly remembered when Clark became what he would later be called a “cross-dressing cannibal killer.”

“I immediately noticed those icy blue eyes,” Luciano said. “He has no soul. You can just sense that there is evil emanating from this man. You can immediately sense that he is a manipulative man. The chief said, 'If he gets away, we have to put him on the ground,' and that's exactly how I felt.”

“When I saw this guy, my immediate reaction was to pull out a gun, put it to his temple and pull the trigger. When you're in front of this guy, there's just an evil aura about him. That's what emanates from him.”

The documentary series revealed how Clark, who was diagnosed with paranoid schizophrenia, began exhibiting strange behavior as a child. Clark's brother recalled once watching Clark hit him on his bike and leave his head bleeding profusely.

His mother claimed that a botched forceps delivery that resulted in head injuries was the cause of Clark's behavior as he grew up. Doctors believed Clark had suffered brain damage.

Hadden Clark had an apparently ideal childhood, but deep down it was something else. (Research and discovery)

Growing up, Clark dissected animals, was bullied by other children, his parents were said to be alcoholics and would fight in front of him and his siblings, and he was once seen wearing women's clothing.

As an adult, Clark attended the Culinary Institute of America but was unable to keep a job – once shocked by a co-worker who saw him drinking cow's blood.

That was just the beginning.

“Hadden Clark has an incredibly intense and angry personality when he doesn't get his way,” Luciano explained. “He lashes out whenever he sees someone weaker than him.”

On May 31, 1986, Michelle Dorr was staying with her father, Carl Dorr, whose house was near where Clark was staying at the time. She was last seen wearing a pink and white polka dot swimsuit and heading to the backyard pool.

That day, the six-year-old boy disappeared, and Carl, who was going through a bitter divorce from his ex-wife, was initially seen as the prime suspect.

Clark later admitted to killing the child and drinking her blood. In 1999, he was convicted of murdering Dole.

The documentary series revealed how Clark told Truitt he knew where Doll's body was located, and in 2000, he led police to the woods where her body was found.

Over the years, Clark created hundreds of works of art that appear to depict his crimes.

“His paintings are mostly women, landscapes and maps,” Luciano says, “like postcards that say, 'If you were here, I could kill you.' I am in some of them… but always as a big girl with blue eyes.”

Hadden Clark worked as a gardener and handyman for Laura Houghteling's mother, Penny. (Research and discovery)

Laura Houghteling disappeared from her home in 1992. At the time, Clark was working as a gardener for Laura's mother, who was 23 years old.

Bloody fingerprints left on the Harvard graduate's pillowcase were identified to Clark, who pleaded guilty to second-degree murder in 1993, and led police to her shallow grave. The Washington Post Reported.

In the documentary, Hoteling's mother, Penny, was described as being affectionate towards Clark, but when her daughter came home from school, Clark's attitude changed.

“Penny began showering her daughter with attention and affection, who was now her primary focus,” Luciano said. “Clark did not take the rejection well at all. His immediate reaction was to become enraged and murder Laura.”

Clark claimed that his alter-ego, Kristen Bruffin, was responsible for the murders.

“When we interviewed him, there were times when he thought he was Kristen,” Luciano said. “He had a wig on. And he had alternate personalities… All of his alternate personalities were women. And he had women's clothes at his campsite. He wore women's clothes. But he loved the attention. He loved people looking at him.”

Murder seems to run in Clark's family: his brother, Bradfield Clark, has been in prison since 1985. Clark murdered a co-worker, Patricia Mack, after inviting her to dinner, then cooked and ate parts of her body.

Luciano thanked Truitt for helping investigators provide closure for the grieving family.

“When Hadden began to confess to Jack that he thought he was Jesus, Jack said, 'Hey, this guy's talking about killing little children, disemboweling them, eating human flesh and slitting women's throats,'” Luciano said.

“Jack took a huge risk in doing this…he's in prison. Calling the police while in prison can have a very negative impact on your health record. But Jack picked up the phone and made the call.”

“I never heard Jack say, 'If I help you guys, you'll let me out of here, right? I've been here for over 30 years,'” Luciano continued. “He never asked for anything. He never asked for attention. He never asked for special favors. And Jack's a tough guy. He was a big-time commander in the system. He wasn't a tamper-evident guy. Now he's an eighth of what he was, but I have a lot of respect for him.”

Luciano said he could not rule out the possibility that there were other victims.

“Hadden Clark is a spoiled brat,” he said. “If he doesn't get his way, he doesn't want attention, and he gets angry. Hadden is not the kind of guy who does things for free, or does things for goodness' sake. If he wants attention, he'll do something to get attention. I'm not saying never, but I don't see Hadden Clark as the kind of guy who would make a death-bed confession.”

Luciano said he hopes the documentary series will showcase the tireless efforts of police who are dedicated to solving cold cases, but also serve as a warning to women.

“You should never let your guard down,” Luciano said. “You never know if the next Hadden Clarke is lurking around the corner. Whether they were dropped on their head at birth, or they're just mentally ill, or they claim their father did all of these things, it doesn't matter to the potential victim.”
