Denver police are considering whether to file charges in a school bus accident that sent at least 14 children and three adults to hospitals.
Police spokesman Sonny Jackson says the investigation continues.
Officials say the bus hit a parked car, then traveled across several lawns before crossing a street and crashing through the wall of a house.
No one was seriously injured.
Denver Fire Department spokesman Phil Champagne says witnesses indicated the driver may have been turning around to grab a sweater behind her, struck the vehicle, turned around and tried to hit the brake but hit the gas pedal instead.
Denver Public Schools spokesman Mark Stevens says 58 year old driver Katherine Sierra is on administrative leave.
She has been a district driver since October 2002.
