Convicted in 1990 for the murders of Swedish tourists Urban Höglin and Heidi Paakkonen, David Tamihere has continued to to protest his innocence and make appeals against his conviction. Controversy surrounding the double murder revived in 2008 when the producer of TV series The investigator, Bryan Bruce, asserted that Tamihere had an accomplice when he murdered the pair. In his book on New Zealand murders, Hard cases, Bruce said that Tamihere was rightly convicted of these murders, but deserved a retrial on the basis of the forensic evidence available after Höglin's body was discovered in October 1991. Tamihere was released on parole in 2010 after serving 20 years of his sentence.
