That's what 17 year old Daniel Jeffrey Martin from Desert Vista High School heard from his mom one day while driving near a piece of the desert near his home town of Phoenix, Arizona. "Huh?" he asked. His mom, a forensic scientist (think: CSI), explained to him that when dead bodies are found in the desert by animals like coyotes, bobcats, and wolves, these scavengers will usually eat them—except for the bodies of methamphetamine users (proven by an autopsy).
