Two people died and two others, including a 2-year-old boy, were left in critical condition following a head-on traffic collision on Kuhio Freeway in Kealia on Friday.

According to police, a Nissan Cube driven by a 28-year-old Kapaa man was heading south on the highway, in an area fronting St. Catherine Cemetery, when it apparently crossed the center line and collided with an oncoming delivery truck shortly before 9 a.m.

The driver of the Nissan died at the scene. A 26-year-old female passenger, also from Kapaa, was transported to Wilcox Medical Center, where she was later pronounced dead.

Another passenger, a 28-year-old Kapaa woman, was also transported to Wilcox Medical Center in critical condition.

The 2-year-old boy, who was riding in the front passenger seat, was flown to the Queen’s Medical Center in critical condition.

The driver of the delivery truck, a 54-year-old Kapaa man, did not sustain serious injury.

Police closed the highway in both directions for more than three hours while investigators scanned the scene and crews worked to remove the vehicles and clear debris from the roadway.
