PHOENIX—A hot air balloon pilot had an elevated level of an anesthetic in his system at the time of a January crash that killed four people in southern Arizona, according to a newly released autopsy report.
Toxicology tests showed Cornelius van der Walt had a high amount of ketamine in his blood when the balloon plummeted about 2,000 feet (609 meters) to the desert floor, the report from the Pinal County Medical Examiner’s Office said.
