LOUISVILLE, Ky. (WDRB) -- A teen accused of killing two sisters when she crashed into an Indiana home was allegedly speeding and under the influence.

Police say 17-year-old Alia Sierra tested positive for opiates and was driving at least 107 miles an hour when the crash happened.

Passengers say Sierra said her car was a beast and talked about how fast it could go.

Two sisters, 17-year-old Haleigh Fullerton and 9-year-old Callie Fullerton, were watching television in their Clinton County living room when they were hit. Both were killed on impact.

Sierra faces a long list of charges including reckless homicide.
