BIRMINGHAM, Ala. — Two court-appointed lawyers who represented Amy Bishop before she pleaded guilty to shooting six colleagues, killing three, at the University of Alabama in Huntsville will receive about $550,000 from the state for their work, and more payments could be coming.

Circuit Judge Alan Mann ­ordered a payment of $452,681 Tuesday for Barry Abston, one of three attorneys who represented Bishop at taxpayer ­expense on capital murder and attempted murder charges after she was declared indigent.
