Investigators continue looking for clues to vandalism at Seashore Hall and Spence Laboratories at the University of Iowa Monday. U-of-I spokesman Steve Parrott says there was extensive damage from the vandalism, and the buildings remain closed. He says they were able to determine spilled chemicals were not a hazzard, so several F-B-I agents have been able to get into the building and take over the investigation. Parrott says students and faculty are still being kept out of the building. He says it’s an inconvenience for several people, although he’s not sure the exact number. He says three departments, journalism, psychology and sociology have been displaced. The preliminary investigation indicated that most of the damage was in Spence Labs and in the east wing of Seashore Hall.
