A 37-year-old man killed when his motorcycle collided with a pickup truck on Kunia Road Sunday evening died of multiple blunt force injures, the medical examiner said, following an autopsy.

The medical examiner identified the motorcyclist as Erric Odom, of Waianae.

Police said Odom was headed south on Kunia Street at a high rate of speed at about 6:11 p.m. when his 2005 Harley Davidson motorcycle collided with a 2005 Toyota pickup truck driven by a 33-year-old Waipahu man, who was making a left turn into a cane haul road about two miles north of Kuoo Street.

Ejected from the motorcycle, Odom suffered head and internal injuries. He died at the scene, police said.

Odom was not wearing a helmet, police said.

His death marks the 46th traffic fatality on Oahu this year, compared to 54 deaths at the same time last year.
