Honolulu police opened a second-degree murder investigation after officers discovered the body of a male in a stolen vehicle in Wahiawa this morning.

“There are suspicious circumstances,” said Sarah Yoro, spokeswoman of the Honolulu Police Department said in an e-mailed statement.

The Honolulu Medical Examiner’s Office said positive identification of the male is pending.

Officers closed Kamananui Road between Kaukonahua Road and Kamehameha Highway after Honolulu police received a 911 call at 6:30 a.m. and responded to the area.

Detectives appeared to be searching an area covered with tall grass on the Haleiwa side of Kamehameha Highway, across from the Green World Coffee Farm.

An employee at the coffee farm said police advised them to secure their gate on Kamananui Road during the investigation. The gate on Kamehameha Highway remained open to the public.

A police helicopter hovered over the grassy area and a vehicle from the medical examiner’s office was observed parked along the eastbound shoulder of the highway near the intersection of Nui Avenue. Yellow police tape stretched across grassy areas along sections of both the westbound and eastbound shoulders of the highway.

A motorist who drove by the scene at approximately noon observed a tow truck hooking up a gray, four-door sedan with a broken rear window covered with plastic.

Police reopened Kamananui Road about 1:30 p.m.
