An Oslo police investigation initially cast suspicion on Erik Mørk Andersen, a Danish truck driver who died in the disaster and who had three previous convictions for arson. A later investigation in 2009 determined that there were several separate fires and that multiple people would have been needed to start them, especially if they were not familiar with the layout of the ship. A 2013 report prepared by a self-appointed Norwegian group called "Stiftelsen Etterforskning Av Mordbrannen Scandinavian Star" ("Foundation for Arson Investigation Scandinavian Star") denied that Andersen was responsible, claiming instead that multiple fires were deliberately set and the truck driver was killed by one of the first two fires (up to nine hours prior to the last fire being started).
