A California woman is suspected of killing her two daughters before unsuccessfully attempting to take her own life in their house, police said.
The children, a 14-year-old and 4-month-old, were found in the garage by their father after he returned home from work about 4 p.m. Tuesday, Ontario police said.
Attempts to revive the girls were unsuccessful.
Their mother was found at the home injured and unresponsive, officials said.
The unidentified woman allegedly left two suicide notes — one in the home and one in the garage — that indicated she planned to kill the children and herself, Ontario Police Department Sgt. Bill Russell told reporters.
He declined to provide further information regarding the contents of the notes.
The mother was taken to a hospital and is in stable condition, but has been unresponsive due to her medical condition, officials said.
She has not been charged because she has been unable to provide police with a statement.
The father, who Russell said was “distraught,” was never detained and gave a voluntary statement to police. He told police last saw his two children alive when he left for work that morning, Russell said.
"He's lost everything at this point," Russell said of the father, calling the case a "horrible tragedy."
Signs of a struggle, which may have been a factor in the girls’ deaths, were present in the home and both children had “visible injuries,” Russell said.
Russell would not specify how the children died, only noting that carbon monoxide poisoning had been ruled out. The teen had special needs, Russell said without elaborating.
He said “the mother was dealing with depression” but would not say if she was being treated for her condition.
