One more police officer, a retired sergeant, still faces trial in late September on cover-up charges. Later officers arrested Lance on the scene and charged him with eight counts of attempted murder of police officers. A total of 20 current or former New Orleans police officers were charged last year in a series of federal probes.
Convicted in the shootings were New Orleans police Sgts. Robert Gisevius and Kenneth Bowen, Officer Anthony Villavaso and former officer Robert Faulcon. Police arrested Lance Madison on attempted murder charges, but a grand jury later cleared him.
