Book excerpt: Wealthy rural Arizona stockbroker Steven DeMarco stands accused of bludgeoning his ex-wife to death with a golf club on the eve of his first $6,000 alimony payment. But theres no DNA evidence, no murder weapon, and he has an alibi. Or, does he? As the determined sheriff's investigators dig into the murder of Carol Washington, a popular local therapist, counselor and artist, they find multiple girlfriends and boyfriends, one home and two condominiums, motorcycles with GPS maps of Mexico, and three BMWs, all being used by DeMarco, his two daughters and the murdered ex-wife. Based on a true crime story, covered by CBS, NBC and ABC News departments we quickly see some of the surprising pieces of evidence found by investigators such as books on how to commit crimes and not get caught, and a backpack hidden on a golf course with a passport and cash inside.
