Preliminary findings indicate that a middle-aged man whose body was found in Koko Crater Botanical Garden this morning did not die of suspicious circumstances, police said.

The case has been classified for the time being as an unattended death, pending the result of an autopsy by the city Medical Examiner’s Department. His identity is also being withheld until then.

The man is not believed to have been a Hawaii resident, police said.

The Honolulu Fire Department had been search the area since Thursday afternoon for a possible missing person.

Capt. Terry Seelig, the Honolulu Fire Department spokesman, said police asked firefighters to help search for the occupant of a car that was parked for more than 24 hours at the city park at the end of Kokonani Street.

Seelig said the department’s helicopter conducted an aerial search until nightfall Thursday.

The search resumed at 6 a.m. today and firefighters found the body of the man in the park about 7 a.m.

Police said the car and the victim are linked.
