Living with Murder also provides readers with an in-depth analysis of murder from a Forensic Psychology perspective. Where does the urge to kill come from? Is it genetic, hormonal, biological, or cultural conditioning? Do killers, rapists, kidnappers and predators have any control over their desires? What sets them apart?
