[1] Alvar and his family lived at a farm called Sundslätt at the southeast part of the island Sirkö in Åsnen, one of the largest lakes in Småland.
The initial search party consisted of the family, neighbours, two police officers, a privately owned German Shepherd and the Home Guard.
In the early morning, Harald contacted the police and informed them Alvar still had not returned, and yet another search soon started.
However, it is hard to explain why Alvar would not have dressed up more with heavier shoes, eaten breakfast, brought his money and/or used his bicycle if he had planned to leave.
It is just short of a kilometre from Sundslätt to the lake, and there is speculation that Alvar suddenly decided to row out in a boat.
Although he had been celebrating the 50th anniversary of his wedding on the day Alvar disappeared and had been working the night before, the grave was opened.
The police immediately assumed the skull belonged to Alvar and using his dental record, this theory was confirmed.
Although there was a big hole in the back of the skull, experts could not determine whether the damage was from a fatal blow or had been caused by weathering during the years since the boy's death.
The skull of Alvar has since been buried alongside of the boy's father and any crime involved with the disappearance has been barred under the statute of limitations.
