American Ripper

Was Jack the Ripper an American? American Ripper In London follows Jeff Mudgett, the great-great-grandson of America's first serial killer, HH Holmes, as he investigates the possibility that his relative could be the infamous killer. After 20 years searching for the truth about his notorious ancestor, Mudgett partners with ex-CIA analyst Amaryllis Fox to launch a new investigation. By exhuming Holmes' body, and using modern technology, the pair aim to solve one of the greatest cold cases of all time. Herman Mudgett, alias HH Holmes, is believed to be responsible for killing as many as 200 people in the late 19th century. An opportunistic con-man, the crowning achievement of his dark deeds was the construction of a building later dubbed the Murder Castle: a hotel on Chicago's south side that he engineered to be a factory of death, complete with gas chamber, dissection room, trap doors and a basement furnace. Around the time of Holmes' killing spree, a killer was terrorising the streets of London. Could they be the same person? (History Channel)
