One year ago today, members of the Animal Liberation Front vandalized Spence Labs and Seashore Hall at the University of Iowa. They removed animals, spilled chemicals and damaged computers.

Psychology Department Chair Gregg Oden says all research programs are now back up and running. But he says things will never be like they were before the attack. "It was a trying year...it was also a time where the department really came together in support of each other."

Last year at this time a police officer was located at this door with the building...under complete lock down. Now the building has opened up a little to students. However there are more security features in place. "Some of it is of course some of the physical things that you can do...but a lot of it has to do with general awareness and alertness...people paying attention to who's around."

Despite the lack of arrests so far, researchers at the University of Iowa hope their upgraded security will prevent similar attacks. The FBI says it's getting closer to catching the vandals, but won't say how soon arrests might come.
