The postcard in question included an aerial map of what social media users say is of Jackson Park along with the words, "I said she dumped me, but really, I dumped her (body)" and an arrow pointing to a specific spot on the map.

That image was uploaded Saturday night and prompted a flurry of reaction online and a police search.
