QUANTICO, Va. — A Marine who shot two of his colleagues to death and then killed himself was a tactics instructor at a school that tests Marines who want to become officers, military officials said Saturday.
Sgt. Eusebio Lopez, 25, gunned down 19-year-old Lance Cpl. Sara Castromata and Cpl. Jacob Wooley, 23, on Thursday night inside barracks at the Marine Corps Base Quantico in northern Virginia. Other than to say the three Marines worked together at the school, military officials have not described their relationship or released a motive for the shooting.
