On the morning of 16 June, the body of the unidentified man was discovered at Rosses Point beach, a popular recreation destination and fishing area near Sligo.

It was the subject of a 2013 documentary, The Last Days of Peter Bergmann, which was shown at the 2014 Sundance Film Festival and has developed a small following on social media websites such as Reddit, where readers have constructed theories of the case.

[3] On Friday, 12 June, the man was first spotted at the Ulster Bus Depot in Derry between 14:30 and 16:00 local time (15:30 and 17:00 UTC).

"[4] He had a slender build, stood 1.79 metres (5 ft 10 in) had short grey hair, blue eyes, a tan complexion, and appeared to be in his late 50s or early 60s.

During his stay at the hotel, the man was seen on CCTV footage leaving the building with a purple plastic bag full of items or personal effects.

Authorities were unable to identify what he threw away in the public rubbish bins, as the man used the blind spots of the surveillance cameras to his advantage.

[3] On Saturday, 13 June, the man was seen walking to Sligo post office at 10:49 (11:49 UTC) and purchased eight 82-cent stamps and airmail stickers.

[3] The following day, the man left the hotel between 11:00 and 11:30 (12:00 and 12:30 UTC) and asked a taxi driver recommendations for a nice quiet beach where he could swim.

At 13:16 (14:16 UTC) he left the shopping centre and walked along Wine Street in the direction of the bus station, still carrying all three bags.

He was wearing purple striped Speedo-type swimming trunks, with his underpants over the top and a navy T-shirt tucked into them.

[1] According to the post mortem report, the body of the man was found on Rosses Point beach with most of his clothes left behind on the shore, with no wallet, money or form of identification.

[7] Some sources say that during the police investigation following his death, it was discovered that the address he gave at the hotel belonged to a vacant lot.

It is unclear how police would have been able to establish that the fake address was tied to a vacant lot, or whether they simply determined that it did not exist.
