The Peter Bergmann Case is an unsolved mystery pertaining to the death of an unidentified man in County Sligo, Ireland. From 12 June to 16 June 2009, a man using the alias “Peter Bergmann” visited the coastal seaport town of Sligo, in northwest Ireland. He used this alias to check into the Sligo City Hotel, where he stayed during the majority of his visit, and was described by the hotel staff and tenants as having a heavy Germanic accent. The man’s movements were captured on CCTV throughout the town; however, the details of his actions and intentions remain unknown. His interactions with other people were limited, and little is known of his origins or the reason for his visit to Sligo. On the morning of 16 June, the naked body of the unidentified man was discovered at Rosses Point beach, a popular recreation destination and fishing area near Sligo. Despite having conducted a five-month investigation into the death of “Peter Bergmann", the police were never able to identify the man or develop any leads in the case. Wikipedia
