A woman who killed six people, including her own sister, in a wrong-way crash on a Southern California freeway has pleaded no contest to second-degree murder.
Twenty-five-year-old Olivia Carolee Culbreath entered the plea Tuesday.
Prosecutors said Culbreath was under the influence of alcohol when she drove east in westbound lanes of State Route 60 in Diamond Bar in 2014.
