The Supreme Court has upheld the conviction of a California woman who said she didn’t know about a stash of methamphetamine hidden inside her car. The case revolved around how much expert witnesses can say about a defendant’s mindset. Delilah Guadalupe Diaz was sentenced to seven years in prison after on drug charges after Border Patrol agents discovered methamphetamine worth nearly $370,000 stashed inside the car door panel as she crossed the U.S.-Mexico border. Diaz contended the car belonged to a boyfriend and she didn’t know the drugs were inside.
