Insights
1Premeditated Murder by a 13-Year-Old
Levi Cart, a 13-year-old boy, meticulously planned and executed the murder of his 64-year-old neighbor, Sheila Tenpenney. He used gloves to avoid leaving DNA and believed his extensive research into serial killers like Ted Bundy would allow him to commit the 'perfect murder' and outsmart law enforcement.
Levi slipped out at a.m., walked to his neighbor's house, put on gloves, and strangled Sheila at a.m. His planning was evident from his years of obsessive research into true crime and serial killers.
2Initial Misdirection and Overlooked Evidence
The investigation initially considered the death self-inflicted, then focused on Sheila's brother, Daryl Tenpenney, due to his unusual certainty that his sister was murdered before paramedics suggested it. A crucial piece of evidence, a men's wristwatch, was overlooked beneath Sheila's body for a week.
Officers initially theorized suicide due to no apparent theft (). Daryl's immediate insistence on murder made him the first suspect (). The wristwatch was found beneath Sheila's body but was initially dismissed as insignificant ().
3Discovery of the Cart Twins and Suspicious Injuries
Detectives shifted focus to Levi and Hunter Cart, 13-year-old twin brothers living across the street, after their mother, Rebecca, mentioned Levi's severe 'cat scratches' that required an ER visit. These injuries were actually defensive wounds from Sheila fighting back.
Rebecca told police Levi went to the ER for cat scratches on his face at a.m. on Sunday (). Levi's over-explanation of the cat attack and the severity of the wounds raised detectives' suspicions ().
4Identical Twin DNA Challenge
DNA analysis revealed that both Levi and Hunter were a match to the blood and hair found under Sheila's fingernails. This presented a unique challenge as identical twins share the same STR markers, making it impossible for the lab to distinguish which twin was at the crime scene.
DNA results showed both Rebecca's sons were a match, but the forensic analyst confirmed identical twins share the same STR markers, preventing individual identification ().
5Overwhelming Evidence Against Levi
Despite the DNA ambiguity, a combination of other evidence conclusively pointed to Levi. This included his journal detailing violent fantasies, an obsession with Ted Bundy, internet searches related to murder and interrogation evasion, a social media post, and physical evidence from his room.
Officers found a journal with violent writing and references to killing in Levi's room (). His phone contained searches on choosing victims, strangulation, and defeating interrogations (). A social media post by Levi read, 'This one was a fighter' (). A shirt covered in Sheila's blood and gloves matching the crime scene were also found in his room (). Hunter identified the watch found at the scene as Levi's ().
6Juvenile Sentencing and Future Concerns
Levi Cart pleaded guilty to aggravated murder, aggravated burglary, and strangulation. Due to his age, he received the maximum sentence under juvenile law, remaining in a juvenile facility until he turns 21. This outcome raised significant concerns among investigators about his potential for future violence upon release.
Levi pleaded guilty on November 10th, 2025, to aggravated murder, aggravated burglary, and strangulation (). He will remain in a juvenile facility until he turns 21, with an expected release in 2033 (). The lead investigator expressed concern that Levi might learn from his mistakes and become more dangerous in the future ().

- Understand the complexities of juvenile justice, where age-based sentencing limits may not align with the severity of the crime or public safety concerns.
- Implement robust evidence collection and investigative strategies that account for unique challenges like identical twin DNA, ensuring all leads are thoroughly pursued.
