"Who" Is the Culprit

Yesterday afternoon

Jian: a tragedy just happened at our zoo. one person bitten to death.

friend: who is the culprit?

Jian: 虎is the culprit.

please pardon me for the pun used. the words "虎" and "tiger" just wont get off my mind. somehow, im very disturbed by this horror incident. the zoo used to be linked with happy images of going there for school excursions, visiting with family and friends. suddenly, its no longer such a happy place.
