\"At times, some people infiltrate our ranks; we got to find them, we got to root them out,\" said McCarthy.

Various investigations continue into the case, including an Army investigation that looked at the family's claims that Guillen was sexually harassed.

McCarthy described Guillen's murder as \"an inflection point\" for service members and victims who have stepped forward with their own stories of sexual harassment and sexual assault with the \"IAmVanessa\" hashtag.

Noting how Guillen's death had resonated throughout the Army, McCarthy said that during a recent trip to Poland and Italy soldiers there asked him about the case.
