A 58-year-old Pepeekeo man died after the motorcycle he was riding struck three vehicles in Honomu Monday.

He has been identified as county employee Malvin Reyes, the Hawaii County officials said.

Reyes was a driver with the Department of Environmental Management’s Solid Waste Division, and had worked for the county for 18 years, officials said.

Hawaii island Mayor Mitch Roth said in a statement, “Our hearts go out to the Reyes ʻohana as we mourn the loss of a dedicated public servant, father, and friend. The sudden loss is felt deeply as we continue to hear stories from his coworkers and other close friends within our office.”

Police responded to a report of a head-on traffic collision in the area of the 13-14 mile markers of Mamalahoa Highway (Highway 19) at about 8:5o p.m.

Police said a motorcycle was traveling south on the highway when it crossed the center line, sideswiped two vehicles and struck a third vehicle head-on.

The three vehicles were traveling north on the highway at the time.

Reyes was taken to Hilo Medical Center where he was later pronounced dead. Police said he was not wearing a helmet at the time of the crash.

It is unknown at this time whether speed, alcohol or drugs were contributing factors.

An autopsy is expected to be performed to determine the exact cause of death.

Police said the drivers of the three vehicles, a 74-year-old man, 23-year-old man and a 24-year-old woman were not injured.

This is the 21st traffic-related fatality on Hawaii island this year compared with 12 at the same time last year.

The East Hawaii Traffic Enforcement Unit has initiated a negligent homicide investigation. Anyone with information on the collision is asked to contact officer Blayne Matsui at 808-961-2339 or email at blayne.matsui@hawaiicounty.gov.
