APNewsBreak: ‘93 mail bomb review clears Ala. prof

BOSTON — A former professor accused of killing three colleagues this year and her brother in 1986 won’t be charged in an attempted mail-bombing in Massachusetts.

Amy Bishop and her husband were questioned in the 1993 mailing of two pipe bombs to Dr. Paul Rosenberg, but never charged. U.S. Attorney Carmen Ortiz reviewed the investigation after Bishop was charged with the shootings at the University of Alabama-Huntsville in February.

Rosenberg received the pipe bombs shortly after Bishop left a job as a researcher at Children’s Hospital in Boston, partly due to a poor review by Rosenberg. The bombs did not detonate.

On Thursday, Ortiz announced her office’s review didn’t find any problems with the investigation, in which no one was charged.

In June, Bishop was indicted in the 1986 shooting death of her brother, Seth.
