Book excerpt: Donna Marie Gentile was an informant for the San Diego Police Dept. Larry Avrech, who was a young officer at the time, stumbled across Donna and the information about her 'sugar daddy' within the department. Recognizing the telltale signs of possible corruption, he befriended the prostitute to dig deeper. It would turn out to be the biggest mistake of his career. Eight months later, Avrech was terminated. His police brothers had chosen to believe a prostitute over a trusted officer "because it fit the specific needs of the department at that particular time". His integrity cost everything dear to him-his career, his home, and later his children. After his termination, the vindictive department continued to threaten him; doing everything they could to preserve their coverup and destroy Larry. Only six weeks after Donna testified against Avrech, her lifeless nude body turned up making Larry an instant murder suspect. In a twist of fate, Avrech got a call from a high-ranking Deputy District Attorney who said he could prove Larry was set up. But the question remained, "Who Killed Donna Marie Gentile?" Larry would work tirelessly for the next seven years to uncover a serial murder and eventually reveal the details in this comprehensive book about what happened behind the sensational headlines.
