(CNN) -- They were all young Marines, all decorated with a slew of awards and all facing a seemingly promising future.
But those futures ended Thursday when one shot his comrades and then turned the gun on himself at a Marine base in Quantico, Virginia.
Lance Cpl. Sara Castromata, Cpl. Jacob Wooley and Sgt. Eusebio Lopez were killed in the shooting Thursday. Authorities say Sgt. Lopez was the gunman.
