Two cops in Wisconsin have worked together for a few years, but were stunned to realize they had an earlier connection. Back in the early 2000s, Sheriff Jim Johnson served in Iraq with the Wisconsin Army National Guard. While he was there, he got letters from schoolchildren. One letter came from a boy named Chris Useldig, who grew up to join the same police force. When he found out, Useldig said he was "stunned," while Johnson said, "It makes you realize how small the world is."
