FAIRFIELD, Calif. (AP) — Authorities believe a Northern California woman stabbed her twin 3-year-old daughters to death before attempting to take her own life and setting fire to their apartment.

Firefighters extinguished the blaze then found the children's bodies about 10:30 p.m. Tuesday inside the burned Fairfield home.

Police say the mother, whose name has not been released, was also inside the apartment with what appeared to be self-inflicted stab wounds. She was taken to the hospital, where she is listed in stable but critical condition.

Fairfield police Lt. Darrin Moody says neighbors who tried to get into the apartment during the fire found the windows and doors were locked.
