NEW ORLEANS - A jury has acquitted a former New Orleans police officer of fatally shooting a man without justification outside a strip mall in Hurricane Katrina's aftermath.

Jurors for David Warren's retrial deliberated for more than 12 hours over two days before acquitting him Wednesday of a civil rights violation and a firearm charge stemming from the September 2005 shooting death of Henry Glover, whose body was later burned in a car by another officer.

Warren testified that he feared for his life when he shot Glover. Prosecutors say Glover wasn't armed.

Warren was sentenced to nearly 26 years in prison after a different jury convicted him of manslaughter in 2010. An appeals court last year ordered a new trial, ruling he should have been tried separately from four other former officers charged in an alleged cover-up.
