The mother accused of killing her two children Aug. 20, including her 14-year-old daughter who attended Chino High, pleaded not guilty Thursday to two counts of murder.
Linda Khanh Nguyen, 47, was arrested at 8:37 a.m. Sunday at Kaiser Hospital in Ontario on several charges after she was medically cleared. She had been hospitalized with unknown injuries since Aug. 20.
Mrs. Nguyen is being held without bail at the West Valley Detention Center in Rancho Cucamonga, records show.
She was also booked by Ontario Police on suspicion of attempting to retrieve a firearm, obstruction of a peace officer and battery on emergency personnel, but the district attorney has not yet decided if those charges will be filed.
Mrs. Ngyuen is scheduled to return to West Valley Superior Court in Rancho Cucamonga at 8:30 a.m. Thursday, Sept. 5 for a pre-preliminary hearing.
She is accused of killing her two daughters, 14-year-old Amy Nguyen and 4-month-old Kaitlyn Nguyen at their home in the 500 block of E. Tam O’Shanter Street in Ontario.
Amy Nguyen was a freshman special-education student at Chino High, and had attended Liberty Elementary and Woodcrest Junior High, both in Ontario and in the Chino Valley school district.
Ontario police said the girls were found inside the garage and two suicide notes were found —one inside the house and another inside the garage.
Both girls had visible injuries, but police declined to say how they were killed.
The girls’ father discovered his daughters around 4:20 p.m. inside the garage.
His wife was found unresponsive, Ontario Police said.
The father is not considered a suspect and has fully cooperated with investigators, police added.
San Bernardino County Coroner’s officials have not yet announced the causes of death as they await results from autopsies.
