Glamorous killer Kaitlyn Conley, 31, breaks her silence in bombshell new docuseries six years after being jailed for poisoning her ex-boyfriend’s mom

Glamourous killer, Kaitlyn Conley, has broken her silence for the first time since she was imprisoned for poisoning her ex-boyfriend’s mother in a new Hulu docuseries. 

Conley, 31, of Sauquoit, New York, was sentenced in 2018 for the 2015 death of Mary Yoder, 60, whom she poisoned with colchicine, a medicine used to treat gout. 

Despite spending two-thirds of a decade in prison, the former receptionist – who worked for Yoder – showed no signs of remorse and rejected responsibility for Yoder’s death in the Hulu series Little Miss Innocent: Passion. Poison. Prison, which debuted yesterday. 

When asked if she killed Yoder, the straight-faced woman’s expression split into a wide grin as she laughed for several seconds before schooling her features. 

‘Sorry,’ she started. ‘No, I did not kill Mary Yoder,’ she finished as stared blankly at the interviewer. 

Conley, who dressed in a demure red sweater and wore glasses, told interviewers that she was ‘unburdening her soul’ and that she ‘sleeps fine at night – despite being in prison’ as she opened up for the first time. 

Conley, who had an on-again-off-again relationship with Yoder’s son Adam, was sentenced to 23 years in prison for the murder. 

Yoder ‘started getting sick’ one day and ‘no one really knew what was happening,’ Conley said Yoder started showing signs of illness toward the end of the day and was ‘running to the bathroom’ until she abruptly left at the end of the day and later ended up in the hospital

The murderer claimed Yoder ‘started getting sick’ one day while they were at the office and ‘no one really knew what was happening,’ she said in the documentary. 

Yoder started showing signs of illness toward the end of the day and was ‘running to the bathroom’ until she abruptly left at the end of the day, Conley claimed to filmmakers. 

In a voicemail to her husband, Bill, the chiropractor told him she was ‘very sick,’ and at one point after she told her spouse goodbye, she moaned: ‘Oh God, help me.’ 

Yoder’s daughter, Tamaryn, said that ‘in less than 48 hours, my mom went from her healthy self to having died.’ 

Doctors had told Yoder she was more than likely experiencing a gastrointestinal disease, which landed her in the hospital later that evening. 

Yoder’s son and Conley’s ex, Adam, messaged the killer to inform her. Conley said the pair had been broken up for around 10 months at that point. 

Conley said she didn’t know ‘how serious it was’ until she arrived at the hospital and saw her boss in the ICU. 

Conley had an on-again-off-again relationship with Yoder’s son Adam, who she thinks has something to do with his mother’s murder as she maintains her innocence 

Conley became a suspect as she admitted to writing an anonymous later that her ex had the gout drug in his Jeep, which turned out to be true. The ‘lightbulb’ moment for investigators was when she said: ‘[Men] don’t use poison, that’s a lady’s weapon’ and smirked at them 

‘She couldn’t talk, she couldn’t move, she couldn’t gesture. And her eyes, she was terrified,’ Bill emotionally told the documentarians. 

When Medical Examiner Kenneth Clark opened up Yoder after her death for an autopsy, he was ‘shocked’ as her organs ‘abnormally’ looked like they had been ‘decomposing,’ he told filmmakers. 

When toxicology reports showed nothing, he went to poison control, who eventually reduced her symptoms down to colchicine poisoning. 

Conley told filmmakers: ‘At the time [she was in the hospital], it really did seem like a mystery, no one really knew what was happening or why.’ 

However, that’s not what prosecutors said. 

Although Adam and Bill were initially suspects in the case, especially after an anonymous letter to police said the younger man had a bottle of colchicine in his Jeep, which was true. 

The spotlight eventually shifted to Conley after investigators asked her to come in for questioning since she had a strong connection to the family and worked for Yoder.

Yoder’s daughter, Tamaryn, said that ‘in less than 48 hours, my mom went from her healthy self to having died’ 

Throughout her interview, she kept pointing fingers at her ex, which got Investigator Robert Nelson suspicious. 

‘During the interview, she keeps talking about how suspicious Adam was acting. You know, in my mind, all of a sudden, she’s pointing a finger at Adam similar to the letter,’ he said. 

When fellow Investigator Mark Van Namee asked Conley if she had been the author of the letter, she admitted she was.

Another moment that incriminated Conley for investigators was when she told them ‘[Men] don’t use poison, that’s a lady’s weapon’ and smirked at them.  

‘That was, like, maybe the light bulb moment,’ Van Namee said. ‘We were convinced that we had the right person.’ 

Conley claimed her and Adam’s relationship was toxic and that he love-bombed her and was ‘really intense’ and would become ‘physically violent.’ She also accused him of sexually assaulting her and trying to strangle her, as well as saying he would get ‘blackout’ drunk. 

In the original trial, Conley had a hung jury. After a second trial, she was found guilty of first-degree manslaughter and sentenced to nearly a fourth of a century. Her team of attorneys, as well as herself, have continued to maintain her innocence and have filed multiple appeals

Conley also allegedly cheated on Adam with one of his close friends, a claim she denied to filmmakers. 

‘He was just as toxic as Katie, as far as not being a healthy relationship for either of them,’ Tamaryn said in the documentary. 

Despite the turmoil between the Conleys and the Yoders, the convicted criminal said she still misses her boyfriend’s mother. 

‘I miss Mary,’ Conley told filmmakers before carefully choosing her words. ‘I really hate that this situation has kind of colored my relationship with her. Because I feel like I can’t really miss her because I’m fighting for my own life.

‘So something I look at all the cards on the table and say: “Oh my god, it must have been Bill,’ she said slowly. ‘And then I look at other things and say: “No, no, no, Adam must have been involved too.’

Adam and his mother had a testy relationship in the months leading up to her death, a clue Conley claims shows he must be involved in her death.  

‘I know it wasn’t me,’ she said as she tried to hold back a smile as she continued to deny responsibility. 

In the original trial, Conley had a hung jury. After a second trial, she was found guilty of first-degree manslaughter and sentenced to nearly a fourth of a century. 

Her team of attorneys, as well as herself, have continued to maintain her innocence and have filed multiple appeals. Her team is currently preparing a motion for the appellate division, according to ABC News. 

She is currently being housed at Bedford Hills Correctional Facility in New York. 

‘I hope she never makes it out of prison,’ Tamaryn said. ‘I’d be okay if she made it 22 years and then got killed in there. I’d be happy.’ 

Conley, however, said she’ll keep fighting for her innocence.
