A female visitor from California has died following a motor vehicle collision in Kailua on Friday morning, the Honolulu Police Department reported.

At about 11:30 a.m. today, police said a serious motor vehicle collision between two vehicles occurred at Mokapu Saddle Road near the H-3 freeway. The 48-year-old woman was driving a Toyota eastbound on Mokapu Saddle Road when she proceeded through a red signal and collided with an Audi driven by a 33-year-old man from Kailua.

Police said the man is believed to have had the green light while making a left turn at the time of the collision.

The woman’s rear seat passenger, a 79-year-old woman also from California, was taken to Adventist Health Castle hospital in critical condition. The woman later succumbed to her injuries and was pronounced dead at the hospital.

At this time, police said speed, alcohol, and drugs do not appear to be contributing factors in the collision.

This is the 49th traffic fatality on Oahu so far this year compared to 46 during the same time period last year.

Police rerouted Kailua-bound traffic on Mokapu Road to the H-3 freeway for several hours Friday afternoon. The investigation of the collision is ongoing.
