HUNTSVILLE — Lawyers for a former Alabama professor accused of killing three colleagues during a faculty meeting want a state appeals court to delay her March trial because officials haven't paid for expert witnesses or testing by a neurologist.

The Huntsville Times reports that Amy Bishop's court-appointed attorneys say the state comptroller's office and a new office of indigent defense services have refused a judge's orders to pay for the defense experts or the testing.

The appeals court on Wednesday ordered the judge and state officials to respond within 21 days.

A trial date has been scheduled for March 19. Bishop has pleaded not guilty by reason of insanity to charges of capital murder and attempted murder in the February 2010 shootings at the University of Alabama at Huntsville.
