During Tuesday's news conference, Garcia said Vanessa's mom told authorities that her daughter expressed to her that she did not feel safe at the base in Fort Hood and was possibly a victim of sexual assault.
"We need to get to the bottom of this. We need to make sure we look at every single complaint, every single allegation that has been made in this case," Garcia said. "This is very serious. We need to make sure that those concerns are addressed, and we need to make sure there are no questions left."
