Biology professor Amy Bishop is escorted by sheriff's deputies at the Madison County Courthouse in Hunstville, Ala. on Sept. 11.
A Harvard-educated biology professor was sentenced to life in prison without the possibility of parole on Monday after being convicted of shooting colleagues at a faculty meeting, killing three and wounding three others.
The jury deliberated for about 20 minutes before convicting Amy Bishop in the Feb. 2010 shooting rampage at the University of Alabama in Hunstville.
Bishop, who arrived in court with her feet shackled and wearing a red prison uniform showed no reaction as the verdict was read, The Associated Press reported.
"She is shattered beyond belief," attorney Roy Miller said. Miller said that Bishop has often expressed great remorse to the victims and their families.
Colleagues believed Bishop, who allegedly pulled the gun from her purse to start shooting, was angry that the school had denied her tenure.
Bishop killed her boss, biology department chairman Gopi Padila, plus professors Maria Ragland Davis and Adriel Johnson. Professors Joseph Leahy, staff aide Stephanie Monticciolo and assistant professor Luis Cruz-Vera were shot and wounded.
On Sept. 11, Bishop pleaded guilty to killing three people and wounding three others. By doing so, she avoided a possible death sentence with the plea and instead faces life imprisonment.
A trial was still required under Alabama law.
After her arrest in Alabama, authorities in Braintree, Mass., charged Bishop with the 1986 shooting death of her teenage brother.
That death initially had been ruled accidental based on the testimony of the family.
Authorities in Massachusetts are awaiting the outcome of the Alabama trial before deciding how to proceed in their case against Bishop.
