(CNN) The mayor of Tampa has a message for police officers hunting down a mystery killer: "Bring me his head on a platter." The video, taken at different angles, shows the same person seen in the historic Seminole Heights neighborhood in an earlier video released by police. "I've come up with four reasons why this person is running," interim Tampa Police Chief Brian Dugan told reporters. "He may have seen something or heard something," the chief said of the person seen flipping what appears to be a cellphone in their right hand while walking. "That might be a habit of this person," Dugan said of the phone flip.
