OLD ORCHARD BEACH — A 57-year-old woman rescued her grandchild Tuesday, but was unable to save herself from a strong current and died early today, police said.

Anne Farley, 57, of Westbrook dove into the water after her grandchild fell in but got caught in a strong current from the outflow of Goosefare Brook, police said. She and about a half-dozen others were pulled from the water about 2:30 p.m. Tuesday by lifeguards, said Deputy Police Chief Keith Babin.

Farley was unconscious and officers performed CPR until she was taken to Southern Maine Medical Center, Babin said. She was later taken to Maine Medical Center, where she died early today, Babin said.

The others pulled from the water and the grandchild rescued by Farley were all unharmed, Babin said.

Babin said the incident was unrelated to strong riptides that required lifeguards to rescue dozens of people elsehwere in Old Orchard Beach Tuesday.

Farley was a library assistant at The Portland Press Herald/Maine Sunday Telegram from 1980 to 1995 and most recently was librarian at Bonny Eagle Middle School.
