Least competent criminals

Krystal Evans, 26, and Denise McClure, 24, rifled through packages on a DHL delivery truck in December in Crescent City, Calif., looking for their urine samples headed for the lab because they were certain theirs would test positive, which would have meant their return to jail. The driver summoned police, and the women were arrested for destroying evidence and violating their probation. In March, were convicted and could face two years in prison. Evans' original sample turned out to be clean, after all, but during the December arrest, she tested positive for methamphetamine.
