The incident provided probable cause to file weapons and assault charges against her at the time, police said, according to The Associated Press, but charges were not filed and the statute of limitations has expired.
Bishop also was questioned, and again never charged, in a 1993 attempted mail bombing of a Harvard professor.
In 2002, Bishop admitted in court to punching a mother in the head after the woman was given the last booster seat in an International House of Pancakes restaurant in Peabody, Mass., the AP reported.
Bishop apparently wanted a booster seat for her own young child and yelled at the woman, "I am Dr. Amy Bishop," according to the police report.
Peabody police Capt. Dennis Bonaiuto said Bishop admitted to the assault in court and the case was adjudicated, meaning the charges eventually were dismissed.
Finally, in 2009, dozens of Bishop's students signed a petition to remove her after appeals to school administrators failed to get her out of the classroom.
One of the letters was addressed to the biology department chairman, Gopi K. Podila, but in a subsequent meeting with the students Podila dismissed their complaints, student Caitlin Phillips told the Associated Press. Podila was the first person shot when Bishop allegedly began her shooting spree last Friday.
In at least three complaints to administrators, the students said Bishop had unsettling ways, never looked students in the eyes, and frequently talked about her alma mater, Harvard University.
"We could tell something was off, that she was not like other teachers," Phillips told the AP.
