Two children were killed and two more were critically injured in a shooting early Saturday near the Houston suburb of Angleton, Texas, authorities said. The Brazoria County Sheriff's Office said in a Facebook post that deputies responded to reports of the shooting and found two children, ages 13 and 4, fatally shot. "Fortunately, the two injured children are now in stable condition," Madison Polston, the sheriff's public affairs officer, said in an email Saturday. A woman has been arrested in connection with the shooting, Polston said. "While details are still developing, the loss of two children in such a manner is a tragedy," the sheriff's office wrote in the Facebook post.
