(CNN) -- Two New Orleans police officers convicted last year in the killing of a man during the chaos following Hurricane Katrina were sentenced Thursday in federal court.
Former Officer David Warren got more than 25 years in prison, and current Officer Greg McRae was sentenced to more than 17 years, the Justice Department said.
A jury in December found Warren guilty of manslaughter for killing Henry Glover, 31, on September 2, 2005.
He was also found guilty of deprivation of rights under color of law -- a charge that relates to abusing one's status as a police officer while breaking the law.
Prosecutors contended that Warren fired at Glover from the police station's balcony after he allegedly saw Glover heading toward the station with something in his hand.
After Glover was shot, bystanders drove him to a nearby school looking for help. Instead, the men were allegedly beaten by police officers at the school, who then left the school with a car that had Glover's body in it.
McRae had been found guilty of using a fire to commit a felony -- specifically, burning the Chevrolet Malibu with Glover's body inside. McRae burned the car near the police station where Glover was shot, prosecutors said.
The jury also convicted him on three counts of deprivation of rights under the color of the law and found him not guilty on one such count.
Earlier this month, a federal investigation found that the New Orleans Police Department has engaged in patterns of misconduct in violation of the Constitution and federal law, the Justice Department announced.
Among the findings are that the police department has used excessive force, made unconstitutional stops and searches, and illegally profiled people based on race, ethnicity and sexual orientation. The investigation also found a number of practices that contributed to the illegal conduct, including failed systems for recruiting and promoting officers, poor training and lack of supervision, among others.
