The Associated Press reports that a mother who drove the wrong way on an expressway, triggering a three-car crash that killed eight people, had been drinking vodka and smoking marijuana and had a blood-alcohol level more than twice the legal limit, police said Tuesday.

Diane Schuler, 36, who died along with her 2-year-old daughter and three nieces in her red minivan, had more than 10 drinks of alcohol in her system and a high level of the main ingredient in marijuana, authorities said. A broken 1.75-liter bottle of Absolut vodka was found in her wrecked minivan, police said.
