Parents up and down the country are terrified when an unknown blackmailer begins to contaminate baby food. But, as the blackmailer demands more money, police notice a familiar pattern to their speech, leading them to question if this disturbed individual is Rodney Whitchelo, one of their own. Cops Gone Bad covers seven new cases to expose murderers, fraudsters, swindlers, sexual predators and drug dealers within the police force. Will returns with his team of experts: retired Detective Chief Inspector Howard Groves and forensic psychologist Serena Simmons. Also joining them is former Detective Chief Superintendent Sue Hill, who has been investigating serious crime for over 30 years.
