This is the conclusion of a two-part case. Denise Tenpenny, 64, was assaulted and murdered in her bed in Fairfax, Ohio, and the DNA at the scene led investigators 50 feet across the street to identical twin 13-year-old brothers, Hunter and Levi Cart — whose DNA is indistinguishable. Since the genetics can't separate them, the case turns on everything else: Levi's watch found under Denise's body, a torn piece of green nitrile glove at the scene matching a box in his closet, bloody L.L. Bean boots in his room, and a journal whose pages include his name and 'I will kill you' in block letters.
The phones do the rest. Levi's device shows messages to strangers on TikTok about having very low empathy and killing animals, screenshots of serial killers' methods, searches for the Fairfax police department, Ted Bundy's kill kit, and 'ways cops mess with you in the interview' — plus a deleted message reading 'I'm probably going to get caught.' On the night of the murder his camera runs from 2:30 to 2:52 a.m. Hunter's phone, by contrast, is clean: it was off during the crime, and his searches look like a worried neighbor's. Even the family cat, Marshmallow, ends up as evidence — officers notice his claws are too small to have made the scratches on Levi's face, which the family believed came from the cat.
The episode's core is the two interrogations. Hunter spends his insisting his brother is incapable of this, working through every alternative — a planted watch, a lost watch, a meticulous framer — and visibly stopping himself each time the coincidences stack up, until investigators zoom out a crime-scene photo of the watch and he breaks down. Levi's interview is stranger: he oscillates between playing dumb (claiming not to know what geometry or urgent care are) and offering sophisticated theories about blood transfusions and familial DNA, sparring with a detective over whether murderers are 'monsters or people who make mistakes.'
Investigators never get a confession. On November 10, 2025, Levi Cart pleads guilty to aggravated murder, aggravated burglary, and strangulation, receiving the maximum juvenile sentence — detention until age 21, with release expected in 2033. The host speculates the plea may have spared prosecutors a trial over how the interrogations of two 13-year-olds without lawyers present would have held up.
