A Nelson man has been found guilty of the historic kidnapping and rape of a Christchurch man, after forensic evidence taken in Nelson linked him to the crime.
A jury in the High Court at Christchurch on Wednesday found artist Christopher Michael Robb, 44, guilty of sexual violation, kidnap and indecent assault.
The verdicts followed a three-day trial before Justice Christian Whata.
Robb was found guilty of sexually violating the 18-year-old man, kidnapping him and taking him to a rural road near Darfield, tying his hands and indecently assaulting him.
The jury found Robb not guilty on a charge of stealing the young man's wallet.
Detective Senior Sergeant Wayne McCoy, of Nelson, said Robb was arrested in Nelson on separate charges and as a result of that arrest forensic evidence linked Robb to the Christchurch kidnap and rape charges.
Robb was convicted in the Nelson District Court in June on eight charges of sexual grooming after he bombarded two 14-year-old girls with text messages, some of which were sexually explicit and predatory.
He was jailed for 18 months on that charge.
He was found guilty of selling drugs in a separate case in October in the Nelson District Court.
McCoy said it was a good result that forensic evidence was able to assist in solving the cold case, and it was good that the victim was finally able to have the case resolved eight years after it happened.
In the Christchurch case the victim was picked up by a man who found him drunk and sick in Liverpool St in central Christchurch after a night drinking with friends in 2005. The victim was not fully conscious as he was driven out of town.
He could not identify the attacker, but Crown prosecutor Claire Boshier said Robb had been identified through a DNA match years later.
Robb claimed his DNA was found on the youth after consensual sex earlier that evening.
