“Sigma Pi President Zach Smith '13 said in an email Sunday afternoon that the fraternity has "figured out who the perpetrator was, and will turn his name over to police." The individual identified was not a brother of the fraternity, he said. “
ETA See the next post from exlurker. Apparently the perpetrator is a Sigma Pi from another chapter who was just visiting Cornell.
