Multi-millionaire entrepreneur Bill McLaughlin was living the good life in Newport Beach, California, when he was shot dead in his home. This Saturday, 48 HOURS MYSTERY explores the deadly love triangle that may have led to the death of McLaughlin, a murder that rocked this wealthy and glamorous community more than 15 years ago. The broadcast will investigate the story behind McLaughlin's death, including the suspected roles played by his fiancée Nanette Johnston, and former NFL linebacker Eric Naposki, who speaks to 48 HOURS MYSTERY in his first on-camera interview. McLaughlin was a devoted father and family man, who, following a 1990 divorce, began seeing and ultimately became engaged to a much younger Nanette Johnston who was later discovered to have a habit of seeking out wealthy men to date. Following McLaughlin's death, Nanette was questioned by police, but she had an alibi. However, the would-be Orange County housewife had a shocking secret that would soon be revealed: her relationship with former NFL linebacker Eric Naposki, who had his own plans of marrying Nanette. But police never had enough to bring this case to justice. Now, finally, a family and a community will get the answers to who killed Bill McLaughlin.
