The jury stopped short of finding four officers guilty of two counts of murder in the case, although it convicted the officers of gun and civil rights charges, The (New Orleans) Times-Picayune reported.
A fifth police officer who wasn't at the shooting was also convicted of corrupting the investigation and planting evidence.
Two people were shot and killed on the Danziger Bridge on Interstate 10 by police Sept. 4, 2005, days after Hurricane Katrina flooded New Orleans and sent the city into mayhem. Four other civilians were wounded by police.
The four officers involved in the shootings have been in jail since their indictments and face prison sentences ranging from 35 to 60 years, the newspaper said. They all pleaded guilty to the various charges.
One more police officer, a retired sergeant, still faces trial in late September on cover-up charges.
