'' Morris is accused of shooting police officers Jeffrey Kocab and David Curtis during an early morning traffic stop near downtown Tampa on Tuesday . Both men died later at the hospital , according to police . Castor also announced the arrest of 22-year-old Cortnee Brantly , the woman believed to have been driving the car at the time of the shooting . `` She was arrested by Hillsborough County sheriff deputies in Brandon , '' Castor said . `` She is facing federal charges of witnessing a felony and not reporting it . '' Brantly was questioned by police for several hours immediately after the shooting Tuesday , but was not arrested at that time . Funeral services for the two officers are scheduled for Saturday .
