At Worlds of Fun in Kansas City, on the evening of September 13, 2025, during the opening night of the park's annual Halloween Haunt event, an active shooter scare occurred. Reports came in around 9:10 pm local time of possible gunshots inside the park, which prompted a large police response and the evacuation of the attraction. The alarm was triggered after an off-duty officer was alerted by sounds resembling gunfire. Despite the heavy police presence and the evacuation, no shots were confirmed to have been fired, no weapon was found, and no injuries or fatalities were reported. The Kansas City Police Department (KCPD) investigated the incident but could not determine the origin of the noise that sparked the alarm. Multiple disturbances involving juvenile fights broke out, which the police had to break up during the response. The park remained closed for the evening following the incident, and authorities continue to investigate the case. The scare occurred amidst a large crowd due to the Halloween Haunt event, which typically runs through October 31. Witnesses described the situation as frightening, with people running and a significant police presence with officers in riot gear.
