STAFFORD (June 26, 2014) Investigators have determined that a teenager shot his two siblings to death at the family's house in Stafford before taking his own life.
Authorities believe Fahad Mughal, 18, killed Faheem Mughal, 23, and Rebecca Mughal, 15, and then committed suicide.
Their mother discovered the bodies Tuesday.
Stafford police Lt. James Leedom says authorities may never know the motive for the deadly shooting.
Records show officers have been sent to the house eight times since 2005.
Two of those calls involved family violence.
Services are Thursday afternoon in Houston for three siblings.
