Marina Voinova, a Russian woman, was using the maps feature of the Russian version of Google — called Yandex — to look up an address, and when she selected the street view option, she saw her fiance, Alexander, in the arms of another woman.
In the photo, Alexander's arm was in a cast, so she realized that this photo was taken last year when he broke his arm.
When Alexander got home, she confronted him with the evidence by asking him to look up the address. Clever ploy!
He immediately confessed to the affair but said the woman meant nothing to him. Classic excuse, but Voinova ended the relationship anyway.
