Alleged family argument ends in deadly shooting.

According to KHOU, a Houston area woman fatally shot her two daughters, then the police shot her.

It happened Friday evening in the Houston suburb of Fulshear. Fort Bend County Sheriff's office identified the shooter as 42 year-old Christy Sheats, and her victims as 22-year-old Taylor Sheats and 17-year-old Madison Sheats.

No reason was given for the argument that led to the shooting. The police were forced to shoot the mother when she apparently prepared to shoot one of her daughters again.
