At the university, a parcel addressed to Patrick Fischer, head of the computer science department, explodes, injuring his secretary, Janet Smith. Fischer is giving a series of lectures in Puerto Rico when the package is forwarded from Pennsylvania State University, where he taught before coming to Nashville. Canceled stamps were used to mail the parcel from Provo, Utah, causing investigators to consider that the bomb may have been intended for LeRoy Bearnson, an electrical engineering professor at Brigham Young University, who is listed as the return address. Later, the bomber was identified as Ted Kaczynski. One injured.
