Vallejo police say a woman set herself on fire inside her home last weekend, killing herself and her twin 14-year-old daughters.
Capt. Lee Horton said Thursday that 47-year-old Mau Dao’s suicide also injured her 11-year-old daughter.
He says detectives are investigating the case in the Bay Area as a suicide that resulted in two homicides.
Horton says in a statement that the 11-year-old girl is with her father and expected to recover.
Authorities said an officer patrolling the area Sunday saw the girl outside a house that was engulfed in flames.
