A Utah woman charged with killing her husband by poisoning him is seeking to get the charges thrown out over what her lawyers claim is prosecutorial misconduct. Defense attorneys for Kouri Richins filed a motion to dismiss Wednesday, arguing that prosecutors erred when they characterized a jailhouse letter written to family as "witness tampering," even though Richins has not been charged with such a crime.
