SANTA CRUZ, Calif. — Pacific Collegiate School in Santa Cruz says two of its students and one of the students parents were on board the boat that caught fire in Southern California.

There is no word on whether they survived.

The school will have additional counselors on site beginning Tuesday to help the entire school community.

Pacific Collegiate School is a public charter school serving 7th - 12th grade students in Santa Cruz.

Around 3:30 a.m. on Labor Day, the U.S. Coast Guard responded to a mayday call from the dive boat Conception off Santa Cruz Island in Southern California. They found the vessel completely ablaze.

The Coast Guard says five crew members on the bridge at the time of the fire were rescued by a passing good Samaritan vessel, but 34 others, most of whom were sleeping below deck, were not accounted for at the time of the initial rescue efforts.

Twenty-five bodies had been located as of Monday night, the Coast Guard said. Rescuers initially recovered four bodies, and 16 others were pulled from the water later in the day. Five others have been found but not recovered due to unsafe conditions under the boat.

Nine more people are still unaccounted for.

According to the Coast Guard, the boat sank in 64 feet of water while crews were fighting the fire. It was 20 yards from the shoreline of the island in the Channel Islands.
