Police are investigating several new leads in the David McNee murder, including several sightings of his car and an assault on McNee eight months ago. A restraining order was issued last year against a man who physically assaulted McNee over a debt. McNee said at the time that the debt was owed by the previous owner of the house, and that the beating was a case of mistaken identity. There have also been two more reported sightings of McNee's black Audi convertible, at a food outlet in South Auckland and a retail store in Auckland City. Both witnesses reported that there were several people in the car. Two items found in McNee's garden on Thursday have been sent for forensic investigation.
