A 16-year-old girl and her 7-year-old sister—both sleeping in their bedroom in Lancaster—were injured when a suspected drunk driver crashed through the girls’ house, authorities said.

The crash occurred about 1 a.m. Aug. 23 in the 44700 block of 27th Street East, according to Sgt. L. Schreiver of the Los Angeles County Sheriff’s Department’s Lancaster Station.

The 16-year-old, who was pinned between the car and a wall, told paramedics she could not feel her legs and was transported to a hospital, Schreiver said. The younger girl suffered cuts on her face and was treated at the scene.

The woman driver was northbound on 27th Street east when she lost control of her 2011 Nissan Altima at Weingart and it crashed into the bedroom of the house on the northeast corner, Schreiver said.

The driver was taken to a hospital for treatment of ankle pain, he said. She was under arrest for suspicion of DUI, and speed may also have been a factor, Schreiver said.
