An Arrowtown murderer who was brought to justice 16 years after the killing is drug-free and making "excellent progress" on parole, a report says. But that was not enough for Parole Board chairman Sir Ron Young to allow 48-year-old Jarrod Allan Mangels to be free of his GPS tracker.
"This was a particularly horrific murder," he said.
"Mr Mangels has had his struggles in coping in the community after almost 18 years in prison and a long history of violent offending and although he is doing well, we still think it important that we monitor compliance with the geographical restriction."
Mangels strangled his neighbour Maureen McKinnel in Arrowtown on Boxing Day in 1987.
The 38-year-old victim's naked body was found five days later, dumped under the Arrow River bridge but the case was only solved in 2003, when scientific advances meant the killer's DNA could be matched with that found under the woman's fingernails.
