May 1 (UPI) -- Surfers returned to a popular beach in the San Diego area Monday as a woman is "fighting for her life" from a shark attack two days earlier.
Leeanne Ericson was wearing swim fins and wading in the water about 6:30 p.m. Saturday at a popular surf spot called "Church" at San Onofre State Beach, adjacent to Camp Pendleton Marine Corps, when a shark bit her leg.
Thomas Williams, who recently passed his EMT training test, said he and others used a rubber surfboard leash as a tourniquet to stop the bleeding.
"It was definitely to the point, her hamstring was gone," Williams said to the Orange County Register. "If she didn't receive immediate care, it was life-threatening.
"All of the back of her leg was kind of missing."
She was airlifted to Scripps Memorial Hospital in La Jolla, Camp Pendleton spokesperson Sgt. Asia Sorenson.
Christine McKnerney Leidle wrote on a GoFundMe page that her daughter needs several surgeries after a shark "tore her right back leg from her glute to her knee,"
"She's now in Scripps Memorial Hospital fighting for her life," the mother wrote on the website. "She is a single mom with three young children who depend on her. She has a long rode ahead with several surgeries to go."
As of Monday afternoon, $14,170 has been raised.
The portion of the beach handled by the Orange Coast District of State Parks will remain closed until Tuesday, State Parks spokesman Todd Lewis said Monday.
The Camp Pendleton portion will remain closed until Wednesday, according to release by the base Monday.
But some surfers entered the water despite "shark warning" signs.
A few weeks ago, nearby San Clemente beach was under shark advisory when a shark was spotted by lifeguard trainees in the shorebreak.
Last week, an estimated 16-foot great white feasted on a dead whale off the Dana Point coastline.
Nearly a year ago, a shark bit a woman on her while swimming off Corona del Mar, about 25 miles north of Saturday's attack.
