MONTGOMERY, Ala. – The biology professor charged with killing three Alabama university colleagues in a shooting rampage attempted suicide in jail early Friday, according to a person with knowledge of the case.

Amy Bishop, 45, survived and has been returned to a cell at the Huntsville jail after treatment at a hospital, the person said on condition of anonymity.

Bishop’s husband, Jim Anderson, said authorities did not return his calls after news media in Huntsville reported that Bishop was taken to Huntsville Hospital.

Bishop has been at the jail since she was booked on a capital murder charge in the February shootings, which erupted during a biology department faculty meeting. Six colleagues were wounded, three fatally.

The report on her attempt to take her life came the same week that authorities in Boston announced that a grand jury had indicted her for murder in the 1986 shooting death of her brother, 18-year-old Seth Bishop.

Bishop had told police who investigated her brother’s death that she accidentally shot him while trying to unload her father’s 12-gauge shotgun in the family’s Braintree home.

Federal authorities in Massachusetts also are reviewing their investigation into a 1993 attempted mail bombing in which Bishop and her husband were questioned.

Dr. Paul Rosenberg received two pipe bombs in a package mailed to his Newton home shortly after Bishop quit her job at Children’s Hospital following a poor review by Rosenberg. The bombs did not explode, and neither Bishop nor her husband was charged.
