Two people were taken to local hospitals in critical condition Saturday afternoon after they were found unconscious in a stranded vehicle at Kaena Point.

According to Honolulu Fire Department spokesperson David Jenkins, a fisherman noticed the Jeep Wrangler on the a trail popular with offroad drivers and later investigated when he noticed the vehicle had not moved.

The fisherman found the vehicle in a ditch with its engine running, windows rolled up, and muffler submerged in water. He removed both people — a 33-year-old man and a 25-year-old woman — from the vehicle and performed CPR on the man, who had no pulse and was not breathing, apparently from carbon monoxide poisoning. 

Other witnesses called 911 and assisted with the woman, who was unconscious but breathing.

One of the witnesses drove the man to a nearby area where Emergency Medical Services personnel met them and continued CPR on the man. An HFD helicopter was used to transport the woman off the trail, Jenkins said.

Paramedics transported the man to Wahiawa General Hospital. The woman was taken to Pali Momi Medical Center.
