John Cannaday Shottum was a science buff in the 1870-1880s. Shottum bought a cabinet of curiosities from a man who had passed away and created a small museum of his own out of the items. Shottum was a member of the Lyceum and would often contact his friends through that organization for help identifying his newest acquisitions. In the early 1870s, Shottum was in need of a curator, so he hired Leng in exchange for use of his third floor. In 1881, Shottum became suspicious that Leng was doing something dangerous or illegal in his third floor lab. Shottum investigated the lab and found nothing. However, in the basement, Shottum discovered that Leng was doing experiments on living humans. Before Shottum could do anything, however, Leng killed him and burned down the cabinet.
