Retired FBI Supervisory Agent Jason Pack told Fox News Digital “people want answers,” noting there’s an intense amount of pressure on law enforcement.

“Parents want to know their kids are safe. Students want to know if they can move freely on campus. Families of the victims want justice, and they deserve it,” Pack said. “There is also pressure. Investigators feel it. Prosecutors feel it. University officials feel it. Families of the victims carry it every hour of every day. Pressure, however, does not solve cases. Evidence does.”
