The Ontario Police Department is continuing its investigation into the death of two children at a residence in Ontario on Aug. 20, according to the San Bernardino County Sheriff's Department.
The mother of the children, Linda Nguyen, 47, was placed under arrest in connection with the deaths. She remains at a local hospital, but will be booked at West Valley Detention Center on two counts of murder once she has been medically cleared.
Police were called to the 500 block of East Tam o’Shanter Street just after 4 p.m. for “unknown trouble” and found the children in the garage of the residence. The father, who was not home at the time of the incident, had called police when he discovered his two children deceased and his wife unresponsive.
Initial responding officers provided immediate medical aid but were unsuccessful in reviving the children. The mother was transported to a local hospital for treatment due to an apparent attempted suicide.
Investigators discovered strong evidence leading them to believe the mother was responsible for the deaths. Among the evidence is a suicide note left at the scene.
A motive has not yet been determined, but there is information indicating the mother was dealing with depression prior to the incident.
The official cause of death of each child will not be known until an autopsy has been completed by the San Bernardino County Sheriff Coroner's Division.
This is an ongoing investigation and anyone with information is asked to contact the Ontario P.D. at (909) 986-6711 or Detective Jeff Wright at (909) 408-1878.
