The Germania Street neighborhood in Fairfax, Ohio, a quiet residential area lined with wood-paneled homes and manicured lawns, became the epicenter of a nightmare on the afternoon of February 2, 2025, when Daryl Tenpenny arrived at his sister Denise’s house for a lunch date that would never happen. Daryl had not heard from Denise since the previous evening, and she was not answering her phone, prompting him to drive over and check on her. As he approached the property, he noticed the front door was slightly ajar, an immediate red flag for a woman who was known to be meticulous about locking up.
He knocked, and the door swung open, revealing a scene of unimaginable horror.
Inside, Daryl found his 63-year-old sister brutally murdered, her body surrounded by dark red smears and splatters, alongside an array of cleaning products that suggested a desperate and failed attempt to wipe down the crime scene. Two knives, a bent kitchen blade and a carpet cutter, lay near her body, but the medical examiner would later determine that Denise did not die from stab wounds. Instead, she had suffered severe blunt force trauma to the head and ultimately asphyxiation, likely from a pillow still resting on her face when she was discovered.
The brutality of the attack was compounded by evidence that she had been sexually assaulted, and her fierce resistance was clear from the skin cells and hair strands found under her fingernails, indicating she had fought her attacker with everything she had.
Police quickly traced a blood trail from the bedroom through the back door, across the garden, and out the gate, marking what they believed was the killer’s escape route. Despite the chaos, valuable items like Denise’s phone and laptop were left untouched, while her bloodstained tablet lay beside her, signaling that the motive was not robbery but a targeted act of violence. Daryl, reeling from the discovery, was immediately questioned by police, along with Denise’s other close relatives, including her sister and nephews, all of whom provided DNA samples as part of routine procedure.
The initial assumption was that the blood trail would lead directly to the killer, but none of the family members matched the evidence, and none had any apparent motive to harm Denise.
Investigators then turned their focus to registered 𝒔𝒆𝒙 offenders living within a half-mile radius of Denise’s home, identifying three individuals, but all were quickly ruled out. Desperate for a breakthrough, police expanded their DNA sweep to the entire neighborhood, collecting samples from residents in the hope of either identifying the perpetrator or eliminating potential suspects. For more than a week, the case seemed stalled, with no clear leads and a community gripped by fear and confusion.
Then, on February 12, 2025, just ten days after the murder, the investigation took a 𝓈𝒽𝓸𝒸𝓀𝒾𝓃𝑔 turn that no one could have anticipated.
At noon that day, police officers returned to Germania Street, but this time they did not stop at Denise’s house. Instead, they crossed the street to the home directly opposite, where they encountered Rebecca and her 13-year-old twin sons, Hunter and Levi. The family had already been interviewed and swabbed for DNA a few days earlier as part of the neighborhood sweep, and the officers now asked them to come to the station for what they described as a routine follow-up.
Rebecca, visibly unsettled, asked if she needed a lawyer, but the officers offered only vague reassurances, saying everything would be explained at the precinct. The three had just picked up fast food and were settling in for a quiet afternoon, but their plans were about to be shattered.
At the police station, Rebecca was separated from her sons and made to wait in the hallway while Hunter and Levi were placed in separate interrogation rooms. As the minutes stretched on, Rebecca grew increasingly agitated, demanding to know why her children were being questioned and insisting on contacting a lawyer. The officers had confiscated her phone, leaving her unable to call anyone until the boys’ father, from whom she was separated, arrived.
Despite her repeated requests to leave, the police initially told her she could, only to then admit she could not, a contradiction that only fueled her anger and confusion. What Rebecca did not yet know was that the police had found a DNA match from one of the twins at the crime scene, along with a wristwatch belonging to one of the boys lying directly under Denise’s body.
The evidence was damning, but the lab could not immediately determine which twin, Hunter or Levi, was the source of the killer’s DNA. Inside the interrogation rooms, officers tried to maintain a casual atmosphere, allowing the boys to eat their fast food as they asked questions, hoping to glean information without triggering alarm. Hunter was talkative and open, as he had been during the initial neighborhood interview, but Levi’s behavior raised immediate red flags.
He spoke at length but circled around trivial details, offering repetitive explanations as if to ensure the police understood that any anomalies in his story had nothing to do with the murder.
One such anomaly was the scratches on Levi’s face, which were impossible to ignore given that Denise had fought her attacker and left DNA under her nails. Levi had a ready explanation, claiming that his cat had attacked him during the night of February 1 to 2, precisely within the window when Denise was killed. He said he had spent the early morning hours showering and treating the wounds, eventually breaking down in tears from exhaustion and distress, which woke his mother.
Rebecca had indeed taken him to the hospital, where some scratches required stitches, and she had corroborated this story days earlier, adding that she had sent Levi to stay with his father to get away from the commotion of the murder scene. This alibi initially seemed plausible, but as the interrogation progressed, the detectives grew increasingly convinced that Levi was their suspect.
While Levi remained in the dark about the severity of the situation, his brother Hunter and their parents were already being told the truth. Hunter was shown the wristwatch found with Denise’s body and immediately identified it as belonging to Levi. The realization hit him hard, and he reacted with anger and disbelief, trying to defend his brother, but the evidence was overwhelming.
In the hallway, Rebecca and the boys’ father were informed of the watch discovery, and both broke down in tears. Levi had not yet confessed, but the case against him was solidifying rapidly.
That same day, police searched the family home and seized Levi’s phone, uncovering a digital trail that painted a chilling picture of a young mind consumed by violence. In chats and social media posts dating back to September 2024, Levi had written about lacking empathy due to his childhood, claiming to suffer from a personality disorder. He told one user that he had discovered a strong indicator of such a disorder was harming animals as a child, something he said he had done repeatedly.
In November, he wrote that he had killed animals with a knife, adding that he could not hurt a fly because they were too fast for him. His search history included queries about sadism and personality disorders, and on the day of Denise’s murder, he had Googled the Fairfax Police Department.
Levi’s phone was filled with screenshots and images of real and fictional serial killers, including Patrick Bateman from American Psycho and Dexter from the television series, as well as profiles of the BTK Killer and Ted Bundy. Investigators believed he saw these figures as role models, and his online activity suggested he was trying to join their ranks. He had researched how to strangle someone, find the perfect victim, and get away with a serious crime, even turning to ChatGPT for advice on surviving a police interrogation without incriminating himself.
After the murder, he reportedly wrote online that this one was a fighter, a likely reference to Denise’s resistance. The night after his DNA sample was taken, he wrote, I think I just got caught.
Levi was taken into custody on February 12 and held at the Hamilton County Youth Center, where he awaited trial. His lawyers argued that he suffered from cerebral palsy, a movement and posture disorder, and sought to have him released to home confinement while waiting for proceedings, but the request was denied. He spent his 14th birthday behind bars, and the trial began in November 2025, nearly nine months after Denise’s death.
During the proceedings, a prosecutor detailed how Levi had planned the murder for months, researching techniques and targeting Denise as a vulnerable victim. On November 10, 2025, Levi confessed to the murder of his neighbor, and because he was only 13 at the time of the crime, the case was handled under juvenile law.
The court sentenced Levi to remain in a juvenile facility until he turns 21, with mandatory participation in a victim awareness class and behavioral therapy. He is also required to continue and complete his high school education while in custody. The sentence has drawn sharp criticism from Denise’s family, who argue that it is far too lenient for the brutality of the crime.
Ohio law did allow for stricter penalties, but Levi’s confession led to a more lenient outcome. The case has reignited debates about the age of criminal responsibility and how the justice system should handle violent crimes committed by minors, a deeply emotional and complex issue with no easy answers. As the investigation continues, authorities are also looking into online contacts who may have known about Levi’s intentions or the murder itself, though no further updates have been released.
The Germania Street neighborhood, once a picture of suburban tranquility, now bears the scars of a tragedy that has left a family shattered and a community questioning how such evil could emerge from a 13-year-old boy.
