Two adults and a toddler died in a two vehicle head-on crash on the Big Island that may have been linked to speed and alcohol, Big Island police said.

Just before midnight last night, two adults and two children were riding in a station wagon that crossed the center line on Mamalahoa Highway and smashed into an on-coming vehicle driven by a Keaau man.

The crash happened near Mana Road in Waimea.

Both adults and one child in the station wagon died. The other child, an 8-year-old girl, was in critical condition.

Police identified the 30-year-old woman riding in the passenger seat as Suzanne Ng and the 5-year-old boy riding in the back seat as Aidon Ng, both of Waimea. The identity of the driver, a 32-year-old man, was being withheld pending positive identification. 

The driver of the other vehicle, a 1999 Mercury multi-purpose vehicle, was flown in guarded condition to the Queen’s Medical Center.

Police said Suzanne Ng, the 8-year-old girl riding in the back seat, and the driver of the other vehicle were wearing their seat belts. The driver of the station wagon and the boy were not.

Traffic enforcement officers have initiated a coroner’s inquest case, two negligent homicide investigations, and two negligent injury investigations.

Anyone with information on the crash is asked to call Big Island Officer Marvin Troutman at (808) 326-4646, extension 229.

This brought traffic fatalities on the Big Island to 18 this year compared to 19 at the same time last year.
