The Medical Examiner’s office is still awaiting the results of test before releasing the cause of death of a 49-year-old Honolulu man who police believe may have had a medical condition which led to his death last week when he lost control of his truck and hit a guardrail on Queen Emma Street.

Danii Thomas was taken in critical condition  by ambulance May 7 to the Queen’s Medical Center where he died, police and Emergency Medical Services said.

Police said Thomas was driving a gold 2004 Toyota pickup truck heading north on Queen Emma just south of School Street when the truck veered off the road and hit the curb. The truck crossed the southbound lanes of traffic and crashed into a guardrail by the Queen Emma Street overpass, police said.

This was the 20th traffic fatality compared with 23 the same time last year.
