The three U.S. Marines killed Thursday at a Virginia base in Quantico have been identified.
Authorities say that 25-year-old Sgt. Eusebio Lopez of Pacifica, Calif. gunned down 19-year-old Lance Cpl. Sara Castromata of Oakley, Calif. and 23-year-old Cpl. Jacob Wooley of Guntown, Miss. on Thursday in barracks at the Quantico base, reports the Associated Press. After killing Castromata and Wolley, Lopez then took his own life.
Military officials say Lopez was a tactics instructor who joined the corps seven years ago.
Lopez was a teacher at a school that tests Marines who want to become officers and his specialty was machine-gunner. Castromata was a warehouse clerk for the school, and Wooley was a field radio operator and also worked with the school.
The Marines have not described the relationship between the three or released a motive for the shooting.
