In the quiet community of Fairfield, Ohio, the disappearance of 21-year-old Katelyn Markham sent shockwaves through the tight-knit population of just over 40,000 residents. What began as a missing person’s case in August 2011 would evolve into a complex mur*der investigation, spanning more than a decade and crossing state lines. The twists and turns of this case would leave a family in anguish, a community in disbelief, and ultimately reveal a betrayal of the deepest kind.

Background

Katelyn Markham was described by those who knew her as a little eccentric, very creative, thoughtful, and an all-around sweet person. A talented artist from childhood, Katelyn was often seen with a paintbrush tucked into her hair, always on the lookout for her next creative project. In 2011, she was pursuing her passion as a graphic art student at the Art Institute of Ohio-Cincinnati, balancing her studies with a job at a local bridal shop.

At 21, Katelyn seemed to have her whole life ahead of her. She was engaged to her boyfriend of six years, John Carter, and the couple had plans to move to Colorado after her graduation. John, who shared Katelyn’s artistic inclinations, worked as a glassblowing instructor. To those on the outside, they appeared to be a perfect match — two creatives ready to build a life together.

However, beneath the surface of their seemingly idyllic relationship, there were signs of trouble. Friends later revealed that Katelyn had confided her unhappiness in the months leading up to her disappearance. She reportedly felt trapped in the relationship, citing John’s heavy drug use and other behaviors that made her uncomfortable.

The Cri*me

On August 13, 2011, just days before her 22nd birthday and weeks away from her college graduation, Katelyn Markham vanished without a trace. The last known communication from Katelyn was a text message sent to John at 11:36 PM that night. After that, her phone went dark, either turned off, drained of battery, or had its SIM card removed.

When Katelyn failed to show up for work at David’s Bridal the next day, alarm bells started ringing. John Carter called 911 at 8:00 PM on August 14th, reporting his fiancée missing. He told the dispatcher he had last seen Katelyn around midnight the previous night when he left her townhouse.

Upon arrival at Katelyn’s home, police found no signs of forced entry or struggle. Her car was still parked outside, and her dog was found wandering alone inside the house. The only item missing was Katelyn’s cellphone. The scene presented more questions than answers, setting the stage for a perplexing investigation that would span years.

Investigation

As news of Katelyn’s disappearance spread, the Fairfield community rallied together. Vigils were held, rallies organized, and volunteers combed through local parks, waterways, and wooded areas in search of any clues. Even a national mounted search group from Texas joined the efforts, but to no avail.

The investigation into Katelyn’s disappearance was complex and prolonged, spanning over a decade. Initially, John Carter cooperated with the investigation, consenting to a search of his mother’s home where he lived. However, suspicions began to arise when scratches were noted on his neck, which he attributed to an electric razor.

Phone records analysis revealed that both Katelyn’s and John’s phones went dark around the same time on the night of August 13, 2011. Investigators also discovered deleted text messages between John and Katelyn from the hours before her disappearance, raising further suspicions.

In 2012, attention briefly shifted to a neighbor, Gurpreet Kang, who was accused of sexually assaulting a Miami University student. However, he was quickly ruled out as a suspect in Katelyn’s case. As the case gained national attention, a reward for information grew to $75,000, but no substantial leads emerged.

The breakthrough in the case came in April 2013, nearly two years after Katelyn’s disappearance. Human remains were discovered in a remote wooded area in Cedar Grove, Indiana, about 30 miles from Katelyn’s home. Dental records confirmed the remains belonged to Katelyn Markham. Her skull was found in a tied plastic bag, separate from the rest of her remains, which were wrapped in a black plastic construction sheet.

Despite this discovery, it would take another decade before an arrest was made.

As months turned into years, Katelyn’s father, Dave Markham, fought tirelessly to keep his daughter’s case alive. In 2015, he successfully lobbied for the Butler County Sheriff’s Office to take over the investigation from the Fairfield Police Department, hoping fresh eyes might uncover new leads. A private investigator, Jay Ryan Greene, was also hired and conducted numerous interviews, narrowing down his focus to two potential suspects.

Over the years, John Carter participated in three polygraph tests in 2011, 2014, and 2021, all of which reportedly showed deception. As the investigation progressed, investigators gathered circumstantial evidence against John Carter. Inconsistencies in his stories and suspicious behavior were noted, and witnesses came forward with accounts of John’s volatile and aggressive behavior.

In 2022, a significant development occurred when investigators executed search warrants on two properties: where Jonathan Palmerton (a friend of John’s) lived in 2011 and where John Carter had lived with his mother. Items seized during these searches included notes on the investigation, Katelyn’s school papers, an SD card, and poetry about death and killing. Notably, material similar to what Katelyn’s body was wrapped in was also reportedly found.

Legal Proceedings

In March 2023, John Carter, now 36 years old, was arrested at his workplace and charged with two counts of mu*rder. The charges alleged that he had caused Katelyn’s death on or around August 13 or 14, 2011, either purposely or as a result of committing a violent felony offense.

The arrest was primarily based on the circumstantial evidence gathered over the years. This included inconsistencies in John’s statements and behavior following Katelyn’s disappearance, the results of multiple failed polygraph tests, witness statements about John’s temperament and the state of his relationship with Katelyn, and the physical evidence found during the 2022 searches. The location where Katelyn’s remains were found, near a farm owned by the Carter family, also factored into the investigation.

In a related development, Jonathan Palmerton, a friend of John Carter, was also arrested and charged with perjury in connection with the investigation, though this charge was later dismissed.

Initially pleading not guilty, John Carter was released on a $1 million bond with GPS monitoring. However, in a surprising twist in June 2024, he changed his plea to guilty of involuntary ma*nslaughter. The prosecution had subpoenaed more than 50 people for the trial, indicating the extensive nature of their case.

Throughout the investigation and legal proceedings, investigators expressed suspicions about a possible second person involved in disposing of Katelyn’s body, though this remains unproven. This aspect of the case continues to be a subject of speculation and ongoing investigation.

Aftermath and Impact

The resolution of Katelyn Markham’s case left a bittersweet taste in the mouths of her family and the community that had searched for answers for so long. While there was relief in finally knowing who was responsible, the sentence handed down to John Carter — just 3 years in prison — felt woefully inadequate to many.

Dave Markham, Katelyn’s father, expressed his frustration with the outcome: “I do not feel 3 years is justice, not for Katelyn, not for her sister, not for me, her friends, or the entire community that has ached and grieved alongside us.”

The case has had a lasting impact on the Fairfield community and beyond. It serves as a stark reminder of the complexities involved in solving long-term missing persons cases and the importance of persistence in seeking justice.

In memory of Katelyn, her loved ones have organized events like “Butterflies for Katelyn Markham,” featuring art and color — elements that were so central to Katelyn’s life. Trees have been planted, and butterfly-themed tributes serve as a poignant reminder of the vibrant, creative spirit that was lost.
