Woman plunges car into pond with children inside

Later that day, police in the neighboring town of Lewisville responded to a separate 911 call regarding a vehicle that had been driven into a retention pond.

Inside the car was a woman and three children, ages 8, 9 and 12, according to police. Investigators later confirmed that the woman was the wife of the man who was stabbed.

The children were treated at a nearby hospital, where one of them remains critically injured. The other two are in stable condition, police said.

Audreyanna Lagunes, who witnessed the incident, told KDFW that the deep tire tracks indicated that the driver had to have been driving at a high rate of speed before plunging into the pond.

It was not immediately unclear what led to the stabbing and the subsequent vehicle crash. Fen Ong is in jail awaiting the resolution of the case in court.
