Not new.
My First time ever visiting the Georgetown campus, Aug 1993, was a few days after a student couple returning from a date at night were robbed and had their throats slashed. Fatally.
How terrible. My parents were hysterical when I graduated high school and wanted to live in DC. Now that I'm a parent, I see.
