"She knew how to comfort people," Gabriela Castro said. "She was brave ... full of dreams."
Castromata's stunned family told the Bay Area News Group that she was friends with Lopez, 25, but they had not heard of Wooley, who was 23.
Castromata enlisted in the Marines in 2011, the same year she graduated from high school with honors. She joined the military so she could pay her own way through college, even though her father wanted to pay for it, her family said.
After completing boot camp in South Carolina, Castromata was stationed at Quantico. Although she had not been deployed, Castromata — whose last name is combination of her parents' surnames — had been awarded the National Defense Service Medal, the Global War on Terrorism Service Medal and a Good Conduct Medal.
