Key keywords: quadruple amputee cornhole player, heated argument before shooting, deadly Ohio cornhole tournament shooting, 2024 competitive cornhole violence, Blake Haxton shooting case, Chad Keener cornhole dispute, adaptive athlete criminal case Newly unsealed court filings released this week offer a detailed timeline of the fatal shooting that unfolded at a regional cornhole tournament in Dayton, Ohio, on August 17, 2024, leaving 38-year-old attendee Chad Keener dead and two other bystanders with non-life-threatening gunshot wounds. The alleged shooter, 42-year-old Blake Haxton, is a widely recognized competitive cornhole player who lost all four limbs to a severe necrotizing fasciitis infection in 2016, and had become a prominent figure in adaptive sports circles prior to the incident. He was taken into custody at the scene without resistance, and faces formal charges of aggravated murder, two counts of felonious assault, and weapons possession under disability. Court records confirm that the violent outburst was directly preceded by a 12-minute heated verbal altercation between Haxton and Keener, triggered by a disputed scoring ruling during a high-stakes qualifying match for the National Cornhole Championship Series, which carried a $15,000 grand prize for the winning team. Witness statements included in the filings note that the argument began when Keener challenged Haxton’s claimed score, asserting that one of Haxton’s cornhole bags had landed on the edge of the board rather than inside the hole, which would have cut Haxton’s score by three points and cost his team the round. Tournament officials were called to mediate the dispute, and after reviewing slow-motion footage captured by a nearby spectator, ruled in Keener’s favor, a decision that left Haxton visibly agitated and verbally aggressive, per multiple independent witness accounts. Over the 10 minutes following the ruling, Haxton was heard making multiple explicit threats directed at Keener, including telling a teammate standing beside him “that guy is going to pay for ruining this for me” and “I have something that will fix this”, according to court documents. Haxton then left the outdoor tournament venue briefly, returning approximately 8 minutes later with a 9mm handgun secured in a custom adaptive strap attached to his wheelchair, as confirmed by security camera footage submitted as evidence. The shooting occurred moments later, when Haxton approached Keener as he was speaking to tournament organizers to collect his team’s prize money, firing six shots at close range. Keener was struck three times in the chest, while two bystanders standing nearby were hit by stray bullets. First responders arrived within three minutes of the shooting, but Keener was pronounced dead upon arrival at a local hospital. Haxton’s legal team has not yet entered a formal plea, but stated in a preliminary press briefing that Haxton has a well-documented history of post-traumatic stress disorder and chronic pain related to his 2016 medical crisis, and that they plan to explore mental health defenses as the case progresses. Prosecutors have indicated they will seek a sentence of life without parole if Haxton is convicted, noting that the premeditated nature of the shooting, as outlined in witness statements and security footage, rules out any consideration of lesser charges. The National Cornhole Players Association has since issued an official statement announcing that all future sanctioned tournaments will implement enhanced security protocols, including mandatory bag checks and metal detector screenings for all attendees, to prevent similar acts of violence.
