Responding to an 8:08 p.m. call, police determined that a black 2008 Mercedes Benz 280 convertible was heading north on Highway 11 at a very high rate of speed when it lost control and drove off of the roadway mauka, striking the rockwall sign fronting Manuka State Recreational Park. The driver was then ejected from the vehicle. He was transported to the Kona Community Hospital and was pronounced dead on Monday, August 14, 2023, at 1:18 a.m.
A 25-year-old Kailua-Kona man who was a passenger in the vehicle was also taken to the Kona Community Hospital for treatment, where he is currently listed in stable condition.

The man has not been positively identified. An autopsy has been ordered to determine the exact cause of death.
