On the night of September 4, 2016, gunfire in the parking lot of the 7 Flags Event Center in Clive, Iowa, left two men dead: 44-year-old Kevin Lee Hall and 29-year-old Johnny Lee Ollie Jackson. The shooting occurred as a party was ending, and investigators later concluded the two men appeared to have shot one another in an exchange of gunfire. No other suspects were publicly identified and no firearms recovered from the scene had been located at the time of the investigation.

Hall was an entrepreneur who ran a landscaping company and an in-home childcare business. He was described as an advocate for social justice who supported groups such as Mothers Against Violence and Creative Visions, and as a devoted family man who enjoyed grilling, watching sports, dancing and spending time with loved ones. The investigation was hindered by witnesses unwilling to cooperate, leaving key questions about the events that night unresolved.

If anyone who attended the event or has information about the missing firearms or what led to the shooting can help, please share what is known.
