A 23-year-old Hilo man died early Sunday morning following a single-vehicle crash on Kulana Road, a half-mile north of Hawaii Belt Road in Hilo.

Hawaii county police said Marvin Cascayan was driving a 1996 Honda passenger van southbound on Kulana Road when the vehicle went off the road and struck a tree shortly after midnight.

First responders found the vehicle hanging over the edge on an embankment. A tow truck was used to retrieve the vehicle and Cascayan was taken to Hilo Medical Center, where he died a short time later.

Police said speeding may have been a factor in the crash. It was not immediately known if drugs or alcohol were involved.

It was the 23rd traffic fatality on the Big Island this year, compared to 27 at the same time last year.
