Mistaken addresses lead to deadly shootings

A black teen knocked on the wrong door and got shot in Kansas City, Missouri, in one of a series of similar shootings that happened across the country. Ralph Yarl, 16, went to pick up his siblings from a friend's house on Thursday night. However, Yarl rang the wrong bell and was shot by a white homeowner, Andrew Lester, 84.

On the same day, two police officers responded to a burglary call at an apartment in Brooklyn, New York. They shot and killed a 78-year-old resident after he pointed a gun at them. A 20-year-old New York woman was fatally shot after driving into the wrong driveway while looking for her friend's house on April 15.

In early April, three New Mexico police officers responded to a call and knocked on the wrong door; they shot the homeowner after he opened the door with a gun.
