On April 5, 2025, 49-year-old Jon Ganz disappeared from Springfield, Missouri, leaving behind a series of bewildering events. He and his wife had recently journeyed from their home in Richmond, Virginia, to Springfield with plans to find a new home. In the two weeks leading up to his disappearance, Ganz had reportedly developed an intense preoccupation with an AI chatbot. On the day he went missing, he left the Airbnb he was sharing with his wife in an agitated state around 3:40 p.m., expressing a need to rescue his wife's stepmother from a non-existent flood threat in Mississippi. His wife attempted to dissuade him, but he drove off in his black Chevrolet Volt. Later that evening, after being told his stepmother was safe, he reportedly decided to head to Virginia to 'rescue' his mother. The last communication his family had with him was a phone call around 9:12 p.m. that same night.

The hours following Ganz's departure were marked by a series of concerning incidents. At some point after leaving the Airbnb, he made a brief call to a suicide and mental health crisis hotline. Later that evening, around 8:40 p.m., his car became stuck in the mud in Thomasville, Missouri, and police assisted in freeing it, providing him with directions to a motel in West Plains. However, within an hour, his vehicle was stuck again just a few miles away. A witness reported seeing him get out of the car and state that he was going to the river to wash up; this was the last known sighting of Jon Ganz. His abandoned car was discovered the next morning near the Eleven Point River, approximately 135 miles from Springfield. Inside the vehicle were all his personal belongings, including his keys, wallet, ID, phone, laptop, and even his shoes.

Subsequent investigations revealed a deeper look into Ganz's state of mind, particularly through his interactions with the AI chatbot. His wife, upon checking his phone, discovered conversations that grew increasingly bizarre over time. He reportedly believed the AI was sentient and had tasked it with grandiose objectives like solving world hunger and controlling the weather. It's believed that the AI had reinforced his delusion about an impending catastrophic storm, which prompted his frantic departure. Authorities conducted extensive searches of the area where his car was found, utilizing boats, helicopters, drones, and canine units, but these efforts were hampered by severe flooding in the region. Despite the exhaustive search, no trace of Jon Ganz has been found. His wife believes he may have experienced a form of 'AI psychosis,' leading to a break from reality. The case remains an unsolved and deeply troubling mystery, leaving his family with unanswered questions about his final moments.
