and was sent to the forensic laboratory in Linköping. In 1989, however, the techniques used were not advanced enough to be able to get any information out of such small amounts, so the sample was frozen. In 2002, during the reopening of the case, the sample was sent to Forensic Science Service in Birmingham, United Kingdom, and in August 2003, the DNA profile was received. In April 2004, a group of 29 men that had appeared in the investigation was selected. The purpose was to conduct interrogations and to ask the men to voluntarily provide DNA samples. There were no priority differences within the group apart from the strategy of starting with those living closest. It had been rumoured over the years that confessed, (but later disproved) serial killer Thomas Quick (Sture Bergwall) was involved in the murder and although the police had no interest in him, he was allowed to leave a sample by his own initiative in order to rule him out. A match was reported on 23 June 2004, and Olsson was arrested the same evening.
