A former investigator described facing the Maryland murderer who believed his cellmate was Jesus as "like sitting with Satan."

Lou Luciano had a confrontation with "pure evil" and hopes it won't happen again.

"The retired FBI special agent, who has traveled to various holes in North Africa, East Africa, Iraq, and Afghanistan, stated to Planet Chronicle Digital that he had encountered some of the most evil people on the planet. However, he believes that the individual in question is an exception to humanity and does not belong on Earth."

"It’s like sitting with Satan," Luciano added.

A new Michael Bay docuseries on Investigation Discovery (ID) focuses on the life of Maryland murderer Hadden Clark, titled "Born Evil: The Serial Killer and the Savior." The series explores how the 72-year-old made shocking confessions to his cellmate, Jack Truitt, whom he believed was Jesus, which led investigators to solve cold cases linked to him.

The documentary includes interviews with Truitt, Geoff Clark's brother, family members of the victims, and individuals closely associated with the case.

In the 1990s, Luciano took on the case and now, in a docuseries, he recalls vividly encountering "The Cross-Dressing Cannibal Killer," which was later named Clark.

"As soon as I saw those ice-blue eyes, I knew he was soulless and evil. I could feel the manipulation radiating from him. The chief said we had to put him on the ground if he ever got out, and that's exactly how I felt." - Luciano.

"As soon as I laid eyes on this man, my instinct was to draw my weapon, aim it at his head, and fire. The mere proximity of this individual gives off an aura of malevolence. It's almost palpable."

A docuseries unveiled that Clark, who was diagnosed with paranoid schizophrenia, displayed unusual conduct as a kid. His sibling recounted an incident where Clark rammed him with a bike and observed him gush blood from his head.

Clark's actions growing up were attributed to a bad forceps delivery that caused a head injury and resulted in brain damage, according to his mother. Doctors concurred with this assessment.

Clark was bullied by other children, witnessed his parents physically fight in front of him and his siblings, and was caught wearing women's clothing.

As an adult, Clark enrolled at the Culinary Institute of America but struggled to maintain employment. A horrified group of colleagues discovered him consuming beef blood on the job.

It was only the beginning.

"Luciano explained that Hadden Clark has a vengeful temper that is incredibly explosive when he doesn't get his way. He lashes out whenever he has a weaker person in his grasp."

On May 31, 1986, Michele Dorr was staying with her father, Carl Dorr, whose home was near Geoff's, where Clark was staying. She was last seen wearing a pink and white polka-dot bathing suit, heading to a pool in the backyard.

The 6-year-old vanished on that day. Initially, Carl, who was going through a bitter divorce with his ex-wife, was considered the main suspect.

In 1999, Clark was found guilty of killing Dorr and later admitted to drinking her blood.

In 2000, Clark led police to the woods where Dorr's remains were found after telling Truitt he knew where her body was.

Over time, Clark produced numerous artworks that appeared to portray his wrongdoings.

"Luciano stated that his drawings primarily consist of women and landscapes, maps, resembling postcards with the caption "Wish you were here so I could kill you." He is included in some of the artwork, but it consistently features wide-eyed girls with blue eyes."

In 1992, Laura Houghteling disappeared from her home while Clark was working as a gardener for her mother.

When Penny's daughter returned home from school, Houghteling's demeanor changed despite his mother showing kindness to Clark in the docuseries.

"Penny is now the main focus of her daughter's attention and affection, as Luciano stated." "Clark struggled to cope with the rejection and reacted violently, killing Laura."

Clark maintained that it was his alter ego, Kristen Bluefin, who committed the murders.

"Luciano stated that during interviews, the individual sometimes believed he was Kristen. He would wear a wig and had other personalities, all of which were women. At his campsite, he had women's clothing and would wear them. Despite this, he enjoyed the attention and admiration he received from others."

Since 1985, Clark's brother, Bradfield, has been incarcerated for murdering his co-worker, Patricia Mak, after inviting her to dinner. He then consumed some of her body parts.

Luciano credited Truitt for helping investigators bring closure to the grieving loved ones.

According to Luciano, when Hadden began confessing to Jack that he believed he was Jesus and spoke of killing, gutting, and cannibalizing little kids and cutting the throats of women, Jack responded, "Man, this guy's talking about some serious stuff."

"Jack made a call to the police despite the risk of being locked up in a correctional institution. This entry could negatively impact his health record while in prison."

"Jack never once demanded help in exchange for helping others, despite being stuck in the system for over 30 years. He was a tough shotcaller and not someone to be messed with. Despite his tough exterior, Luciano had great respect for him."

There may be more victims, Luciano stated.

"Hadden Clark is a selfish person who only seeks attention when he doesn't get what he wants. He doesn't do anything for free or out of kindness, and if he needs attention, he will do something to get it. I don't think Hadden Clark is the type of person who would make a deathbed confession."

Luciano hopes the docuseries will highlight the relentless efforts of law enforcement in solving cold cases, while also serving as a cautionary message to women, he stated.

"Be cautious, for the next Hadden Clark could be lurking anywhere," advised Luciano. "Despite whether he was born with a mental illness or claims that his father caused it, the potential victims must remain vigilant."

The show "Born Evil: The Serial Killer and the Savior" will air on Sept. 2 at 9 p.m.
