The Berman Murders by Doug Kari

For true crime readers obsessed with learning the full story, get the book that Publishers Weekly calls a "stirring account," and says, "Dogged reporting and expert pacing make this a good bet for true crime fans."
At daybreak on January 6, 1986, a couple on a camping trip in the Mojave Desert set out for a stroll and never returned. The local sheriff eventually discovered that Barry and Louise Berman had been murdered. As years passed and the double homicide remained unsolved, the Berman case spawned speculation and conjecture. To date there's never been an arrest in the case—let alone a conviction. This is the first book to tell the full story of the Berman murders and uncover a likely suspect.
