Thorng Mao wasn't one of them. When he was shot to death in October 1992, he was unarmed and out foraging by himself in the woods of Klamath County. The murder remained unsolved, and members of Mao's group wondered whether the local police took crimes against them seriously. Less than a year later, in June 1993, another Cambodian picker from Raymond was murdered while hunting for mushrooms in southern Oregon. Phay Eng, a member of the same small group of commercial pickers as Mao, was just 22 years old. He was killed while changing his car's tire by the side of a road 30 miles outside of La Grande; he had been robbed of several hundred dollars and all the mushrooms he'd picked that day.
