The heinous murder of a young girl in Reykjavik 1947 seemed to be a desperate cry for help from the murderer. And, he unfortunately decided to go this horrific way to get some attention. Human contact and interactions 34 years later another young girl brutally attacked and abducted by a stranger in the same part of Reykjavik city.

Two attacks on young girls in the east side of Reykjavik shook the nation.

The prelude to the atrocity that led to the death of Svavar was that Svavar and Lóa, his common-law wife, had been out partying the night before the horrific event. Thráinn Hleinar Kristjánsson had also done so, along with his friend Margrét. Svavar and Lóa had been at Hotel Esja, while Thráinn and Margrét were at Hotel Borg. The people had all had alcohol on hand that evening.
Svavar and Lóa had come home shortly after Þrán and Margrét. The two apartments were on the same floor and there was a shared bathroom on the floor. After Svavar and Lóa came home, Svavar had a drink, but Lóa went to the bathroom. When she came out, she met Þrán and they started talking. Svavar then came out and accused Lóa and Þrán of having a date in the bathroom. Some exchange of words followed, but eventually Lóa went into Svavar's apartment and went to sleep. Svavar followed her shortly after and fell asleep. Þrán and Margrét, however, stayed awake and did not sleep at all night.

On April 1, 1979, a 56-year-old man was murdered in his home at Hverfisgata 34. The deceased's name was Svavar Sigurðsson. He had been stabbed to death with a kitchen knife.
The police were notified a few hours after the murder, but it was the murderer who turned himself in. His name was Þráinn HleinarKristjánsson and he was 36 years old. Þráinn also lived in an apartment in the building at Hverfisgata 34.
Svavar had been stabbed in the abdomen, side and neck, but the cuts were both long and deep. It was believed that Svavar had died soon after the injuries were inflicted. As previously stated, Svavar had been dead for several hours when the police were called. It was immediately considered a matter of investigation why neither Þráinn nor Svavar's common-law wife, Lóa Fanney Valdimarsdóttir, had contacted the police earlier.

By 2017 he was in his 60s. He had serious convictions of fraud behind him. All sorts of victims including widows. A man was about to be killed because of his activity.

Reykjavik early 1980s. The wind of the bay is sharp. The houses are quiet. Inside one of them lives a man who helped shape Iceland‘s financial conversation at the national level. A young man will one day be convicted of defrauding his widow of millions.

Björgvin Thor, who was called the most dangerous criminal of Iceland, said he could not believe he would break into a house, threaten a woman to kill her two sons and then rape her violently. Yet a Couple months later he showed he could commit a violent crime and was about to do it again. 

In 1999, I went to the main prison in Iceland and sat across from the so called ´most dangerous criminal of Iceland!” Now that may not sound so scary to someone in the UK or the US, where there are many dangerous criminals. However, In Iceland, this experience evoked a profound sense of apprehension. 
In 1992 a young man was given this not so positive title by the Icelandic media. He had then in a short period of time attacked women in different parts of the country in the most brutal way one can think of. 

Two bank robberies in 1995 were talked about as the perfect crimes, but were they?
