The case is spotlighting campus security, and a new app may aid in the quest for safety.

The Rave Guardian Campus Safety app allows students to create safety profiles to alert friends and family when they are walking alone. It also features a safety timer to alert campus security when a student does not arrive at a planned destination within a certain amount of time. The app has a panic button that, when pressed, alerts campus security of where a student is.
