Cleveland police are reviewing whether they may have missed chances to rescue the three young women held captive for up to a decade in a house where neighbors say they repeatedly reported something was amiss.
In 2004, Cleveland police showed up at the home after one of the suspects, Ariel Castro, a school bus driver at the time, left behind a passenger.
When no one answered, the officers left, officials say, adding that the bus incident was not a criminal matter.
But neighbors say there were more recent calls that could have led to a rescue.
