Investigate the past with Heritage Frederick and historian Mike Dixon on June 8 at 2 pm, as we catch some of history’s elusive criminals. Programs such as Law and Order and CSI have acquainted most people with modern techniques for solving crimes. But for most of our past, sleuths did as much as they could to investigate crimes, but they lacked the most basic of tools. There was not much the sheriff, part-time constable, justice of the peace, and coroner could do, except rely on obvious physical evidence and witnesses. However, as the scientific age arrived, great advances in police science allowed detectives to crack complex cases. Drawing on notorious crimes and real mysteries from yesteryear, this one-hour program shows how science, technology, and professional police practices helped detectives catch and convict criminals and close once unsolvable cases. Mike Dixon is an award-winning historian and author, appearing on the Today Show, Maryland Public Television, the National Geographic Channel and National Public Radio.
