TAMPA, Fla. (AP) - A 22-year-old woman who police say accompanied the man charged in the fatal shootings of two Tampa police officers has pleaded not guilty to a federal charge of failing to report a felony.

Police say Cortnee Brantley was the driver of the car stopped on July 29. They say Brantley's passenger, Dontae Morris, got out and killed officers David Curtis and Jeffrey Kocab.

Police say Brantley drove off as Morris fled on foot. Brantley was later interviewed by police and released. She eventually was charged by federal prosecutors with failing to report that Morris was a convicted felon in possession of a weapon.

Brantley has not cooperated with authorities, and her attorney wouldn't say whether she would start.
