HUNTSVILLE, Ala. (AP) - We're now learning that the Alabama professor accused of killing three colleagues at a faculty meeting on Friday also shot and killed her own brother more than 20-years ago.
Police say Amy Bishop shot her brother in the chest with a shotgun at their home in Massachusetts in 1986.
No charges were ever filed and it was logged as an accident.
The detailed reports are missing.
The current police chief says he's considering launching a criminal investigation into the report's disappearance.
Now a Biology professor, officials say Amy Bishop had just months left teaching at the University of Alabama at Huntsville when she allegedly opened fire on a group of her colleagues, killing three, and wounding three others.
She was to leave after this semester because she had been denied tenure.
Amy Bishop was taken in handcuffs to the county jail and could be heard saying, "It didn't happen."
A husband of one of the professors killed says he was told his wife was at a meeting to discuss the tenure status of another faculty member who got angry and started shooting.
He says his wife had mentioned Bishop before and described her as "not being able to deal with reality."
One student describes Bishop as "very weird."
Another says she signed a petition complaining about Bishop's teaching style.
Bishop joined the UAH biology faculty as an assistant professor in fall 2003.
