A Texas mother shot her four children over the weekend, killing two and injuring the other two, authorities said.

She faces two counts of murder and two counts of aggravated assault with a deadly weapon and is being held on a $14 million bond.

The victims, ages 13 and 4, died in a vehicle, while the surviving children, ages 8 and 9, are in stable condition at a Houston-area hospital.

The mother called 911 after the shooting, and police recovered a weapon at the scene, the Associated Press has reported.

The incident occurred in Angleton, Brazoria County, about 45 miles south of Houston, and authorities are seeking justice for the children.
