New details about shark attack that left mom fighting for her life

SAN ONOFRE -- Two California state beaches -- San Onofre and San Clemente -- remain closed until Wednesday in the wake of a shark attack, CBS Los Angeles reports.

Leeanne Ericson was swimming with friends in San Onofre State Beach West of Camp Pendleton Saturday when a shark "tore her right back leg from her glute to her knee," according to a GoFundMe page that says it's raising money for her medical fund.

The page says that Ericson, a single mother of three young kids, is now fighting for her life at Scripps Memorial Hospital, in La Jolla. 

Her injury was likely caused by a great white or a seven-gill shark, said Chris Lowe, director of the Shark Lab at California State University, Long Beach.

According to some witnesses, Ericson was wearing a wetsuit and fins near her boyfriend, who was on a board, when the shark bit her.

A few weeks ago, Surfline cameras caught two separate incidents of what appeared to be great white sharks breaching off San Onofre State Beach.

Nearly a year ago, a shark bit a woman while she was swimming off Corona del Mar, about 25 miles to the north of Saturday's attack.
