Police are asking for any witnesses who may have seen what happened to a 17-year-old Kalihi boy fatally injured in front of Sandy Beach early this morning to come forward.

It was believed he may have been the victim of a hit-and-run driver, but Honolulu CrimeStoppers Coordinator Sgt. Kim Buffett said an autopsy showed his injuries were not consistent with an auto accident.

Police said he may have fallen out of a car.

There were no other cars in the area when a patrol officer found Boydshiro A. Maycry lying on Kalanianaole Highway at 2:39 a.m. with traumatic head injuries. He died at the scene., police said.

This is Oahu’s 21st traffic death so far in 2013, compared with 21 for the same period a year ago.

Police closed Kalanianaole Highway as they investigated the accident. The highway reopened before 5:30 a.m.
