Speeding killed two motorcyclists in separate accidents this weekend.

The Medical Examiner’s Office identified the 32-year-old man, who was killed at 10:50 p.m. Friday at Waialua Beach Road and Oliana Street, as Nilo Sanchez Castro, Jr.

Police said the Waialua man when traveling east when the motorcycle he was driving collided with a car.

The motorcyclist was ejected from his bike and was pronounced dead at the scene. The 36-year-old driver of the car was not injured. Police said the motorcyclist was wearing a helmet at the time of the crash.

Excessive speed appears to be a factor in the crash, but it is unknown if alcohol or drugs were factors, police said.

Cause of death is pending an autopsy.

The Medical Examiner is still trying to identify the 36-year-old man, who police said was speeding Sunday on Kunia Road when his motorcycle hit a 2005 blue tuck driven by a 31-year-old Waipahu man that was making a left turn near Kuoo Street.

The motorist was thrown from his bike. He was not wearing a helmet. He was pronounce dead at the scene.

Paramedics treated and took a 10 year-old boy, who was riding in the truck, to the hospital in stable condition. Two other people in the truck refused treatment.

There are now 46 traffic deaths, compared to 54 at the same time a year ago.
