The collision resulted in the death of 55-year-old William Simao of Hilo and critically injured 35-year-old Perry Keohuloa, also of Hilo.

From the office of the Hawaiʻi County Prosecuting Attorney:

According to police reports, Fleming, who was operating a 2023 Tesla sedan and attempting to overtake multiple vehicles in heavy fog and low visibility conditions collided head on with a 2020 Harley Davidson, being operated by Simao. The Tesla also impacted a motorcycle operated by Keohuloa. A fourth vehicle, a Dodge Ram 1500 pickup truck, also sustained damage after being struck by debris from the collision. Simao was pronounced dead at the scene and Keohuloa was flown to the Queen’s Medical Center on O‘ahu with life threatening injuries.

Fleming made his initial appearance in Kona District Court on Tuesday morning, where the District Court judge reduced Fleming’s bail from $400,000 to $300,000. He was ordered to appear for a preliminary hearing on September 9, 2026.
