The woman who killed eight people, including herself, when she drove her minivan the wrong way on the Taconic Parkway was a heavy drinker and frequent marijuana smoker, the woman's sister-in-law told investigators. Despite her husband's repeated claims that his wife wasn't an alcoholic or regular drug user, Diane Schuler's in-law revealed to police that the 36-year-old "was a hard drinker" who "used marijuana daily because of the fact that she didn't believe in doctors," according to an attorney representing the families of two men killed in the July accident.
