An elderly woman smashed her car through a Rockville, Maryland, parking garage and into a physical therapy office on Thursday morning, injuring herself and three other people, authorities say.
The car crashed into the office on Parklawn Drive at about 10 a.m. Thursday. Investigators say they don't know what caused it.
"There's not much of a barrier," Montgomery County Fire spokesman Pete Piringer said. "There's a parking space, a little cement, the sidewalk, a grassy area and then the building. It didn't take much effort to get in there."
Piringer says the driver of the car was taken to the hospital, along with a receptionist who was trapped under a desk and debris. Two others were also taken to the hospital. All of the victims have injuries that are not life-threatening.
Several people at the scene were also evaluated.
