The family isn't satisfied by the conclusions of a county prosecutor, who isn't pursuing criminal charges in Black's death, or the medical examiner who ruled it accidental. They're calling for a federal investigation and appealing for help from Gov. Larry Hogan, who already has expressed a personal interest in the case. (AP Photo/Patrick Semansky)
