Andrea rebello

Andrea Rebello, a 21-year-old junior at Hofstra, was killed on May 17th last year when a police bullet aimed at an ex-con who was holding her hostage hit her in the head.

The cop who shot the co-ed is apparently really upset.

The home invasion suspect, Dalton Smith, had the college student in a headlock, using her as a human shield.

The school held a private memorial service yesterday, and Rebello's identitical twin sister, who was unharmed in the shooting, is home with the girls' parents in Tarrytown, NY.
