Today, a murder that has remained a mystery for more than 30 years. New York undercover Detective Dennis Wustenhoff lived in Long Island, New York, with his wife and three children when he was murdered by a bomb that had been planted under his unmarked police car. At first, police suspected he was targeted and killed by one of the dangerous criminals he tried to put away. But then came a shocking twist; Dennis was having a secret affair. Now, more than three decades after Dennis’ murder, his family claims they know who killed their beloved husband and father -- and they want justice.
