FRESNO, Calif. — Rescuers are struggling to recover a pair of bodies from a car that crashed down a cliff two weeks ago and became lodged in the middle of a California river raging with snowmelt, officials said Tuesday.

Thailand’s Consulate in Los Angeles said it believes the bodies belong to two Thai exchange students vacationing in California who were reported missing after they didn’t return to their hotel.

The Fresno County Sheriff’s Office said it can’t confirm the crash victims’ identities, but it is working with the California Highway Patrol and Thai authorities to find a way to retrieve the car and bodies, sheriff’s spokesman Tony Botti said in a statement.

The car went off the road 75 miles east of Fresno in the steep Sierra Nevada mountains. It crashed 500 feet below into the Kings River, swollen with snowmelt after a record breaking winter, officials said.

The two students were believed to be headed to Kings Canyon National Park. A hotel where the students had been staying called police on July 28.

California and Thai consulate officials haven’t identified the students but Thailand’s Foreign Ministry spokeswoman Busadee Santipitaks told media that Thiwadee Saengsuriyarit, 24, and her male friend Pakkapol Chairattanasongporn, 28, were driving along Highway 180 when their car went off a cliff. They had been enrolled at the University of South Florida.

The Fresno County Sheriff’s Office is trying to come up with a recovery plan that is safe for rescuers, Botti said.

A recovery date hasn’t been set.
