The judge presiding over the trial of accused UA-Huntsville shooter Amy Bishop-Anderson has delayed the hearing by two weeks Tuesday.

The former university professor has been accused of killing three colleagues and wounding three others during a campus faculty meeting.

Madison County Judge Alan Mann didn't give a reason for the ruling. The trial was originally scheduled to begin on September 10, but due to the ruling the trial will commence on September 24 in Huntsville, reports Sacramento Bee.

Attorneys for the Harvard-educated biologist have been fighting with the state over payments for expert witnesses they say are needed to prepare her insanity defense.

Bishop is charged with pulling out a handgun and opening fire during a meeting at the University of Alabama in Huntsville in February 2010. She's also charged with three counts of attempted murder for wounding three others.

The Alabama campus shooting of 2010 left the nation in utter disbelief and shock. According to the eyewitnesses, the accused appeared 'perfectly normal' prior to the shooting. She even lectured in her usual anatomy and neurosciences classes.

The suspected murder weapon, a 9 mm handgun, was found in a bathroom on the second floor of the school's building. Bishop did not have a permit to carry a concealed weapon, as required by state law. She was arrested a few minutes later outside the building.

In March 2009, Bishop had been denied tenure at the university and was in her last semester as per university policy. Due to the attention Bishop has attracted as a result of the shooting, previous violent incidents that were somehow related to her have been reevaluated.

She previously drew the attention of law-enforcement officials in 1986 when she shot her brother to death in Braintree, Massachusetts, in an incident officially ruled an accident. She along with her husband were questioned in a 1993 pipe-bomb incident directed toward her lab supervisor.

Prosecutors are seeking the death penalty against Bishop. Now, she's also been charged in the shotgun death of her brother.
