A Marine stationed at Camp Smith was killed yesterday when the motorcycle he was riding rear-ended a car on H-1 Freeway near Kapolei.

The motorcyclist, a 24-year-old man, was thrown from the motorcycle.

He was pronounced dead at the scene, said Bryan Cheplic, spokesman for the city Emergency Services Department.

According to the Honolulu Police Department's Vehicular Homicide Division, a 2009 Suzuki motorcycle was traveling west on H-1 just after 4:20 a.m. when it struck a 2006 Suzuki Grand Vitara from behind.

The driver of the car, a 31-year-old man from Kapolei, was taken to an area hospital in serious condition.

Police said speed was a factor in the collision. It is not known whether drugs or alcohol also were involved.
