A federal jury will return for a second day of deliberations in the retrial of a former New Orleans police officer charged with fatally shooting a man outside a strip mall in Hurricane Katrina's aftermath.

Jurors deliberated for six hours Tuesday before adjourning until Wednesday morning. U.S. District Judge Lance Africk said they informed him that they hadn't "moved forward" in their last two hours of deliberations.

Warren testified on Monday that he shot 31-year-old Henry Glover because he thought he saw a gun in his hand, but prosecutors said Glover wasn't armed and didn't pose a threat.

Warren was convicted of manslaughter in 2010, but an appeals court ordered a new trial. The court ruled Warren should have been tried separately from other officers charged in an alleged cover-up.
