A woman died yesterday afternoon after a car she was in plunged into the ocean at La'ie Point, officials said.

Emergency responders went to La'ie Point after receiving a report that a white car went off the cliff, fell about 25 feet, landed upside down in the ocean and sank in about 15 feet of water at about 4 p.m.

It was not immediately determined what caused the plunge.

Fire rescue personnel from Kahuku fire station removed an adult woman from the driver's side, Honolulu Fire Department Capt. Terry Seelig said.

"They had her out within 15 minutes of their arrival," Seelig said. "She was unresponsive when they pulled her out."

Firefighters were assisted by Ocean Safety officers who arrived on jet-powered water craft with a sled, onto which they carried the woman from the choppy waters to an easier access point on a beach about a half mile away.

City Emergency Services spokesman Bryan Cheplic said paramedics took the woman in critical condition to a nearby hospital, where she was pronounced dead shortly thereafter.
