Three people were killed Saturday and four others were critically injured when a boat capsized off Santa Catalina Island. 

U.S. Coast Guard spokeswoman Sondra-Kay Kneen of the U.S. Coast Guard told the Associated Press that two of the injured people were pulled from the water and appeared unresponsive. 

Kneen said the Pacific Quest, a chartered fishing boat, initially reported the capsizing of the 15-foot skiff off Salta Vedre Point at around 9:30 a.m. local time.

"The waves in the area were reported to be between 4 and 6 feet, and that could have overturned the skiff," she said.

A Coast Guard helicopter rescued another of the boaters from some rocks, while a Catalina Island Conservancy officer located the other injured person on the beach. The bodies of the three victims were retrieved from the water by Los Angeles County Baywatch lifeguard. 

Santa Catalina Island is located 22 miles southwest of Los Angeles.
