 When the brutal murders took place, it was assumed that they were committed by a gang from Stockholm or abroad.It is often stated that the confidence that the murders were strangers and the complete lack of experience in handling such crimes in small Sala, meant that the individual crimes of the Sala gang were seldom or never thoroughly investigated before the final murder in 1936.Apart from the crimes for which the members of the gang were convicted, there are many speculations on other types of criminal acts that the gang would have carried out.
