A full picture of the shooting emerged yesterday when police confirmed that motorists travelling between Taupo and Tokoroa had earlier seen Ginns fire two shots as he chased Ms Glassie's vehicle from the Kinleith turn-off along the state highway right to the Tokoroa police station in Lodge St.
Emergency services received calls about the shots and one motorist followed the chase to the end. Ms Glassie's sister, visiting from Australia, was in the car as well.
Detective Inspector Tim Anderson said: "We've spoken to witnesses who have confirmed that [the on-road shooting]. They thought it was a tyre blowout at first and they turned around and saw him leaning out the window with a shotgun."
Ms Glassie made it to the police station, but Ginns shot her in her car.
While people rushed to her side, Ginns fled. Police are confident the body they found near his car in Mamaku Forest near Rotorua eight hours later is Ginns.
New details have also come to light about an incident at 6.30am on Friday at Ginns' house in Dalmeny St, which police say he still shared with Ms Glassie. It was earlier reported that neighbours found a young woman hog-tied in the driveway.
The woman was taken to Hamilton by police who feared for her safety while they hunted Ginns.
Her father arrived in Tokoroa about midday yesterday from the Far North to look after his distressed daughter and spoke to police.
"I'm going to meet up with her - I think she's far from all right."
The father said the 20-year-old lived in Tokoroa with her boyfriend, who was not Ginns. He said his daughter had been tied with piano wire, nearly "strangled and left unconscious".
He did not know whether the 20-year-old knew Ginns. Mr Anderson said Ginns was the only "similarity" between the assault victim and Ms Glassie.
"They [Glassie and the young woman] are not related and they are not sort of associates as far as I'm aware. That's the focus of our inquiry from today onwards really."
Yesterday afternoon, police had yet to interview the female victims or a man who was with Ginns when he sped from police after the Dalmeny St assault on Friday.
Officers yesterday spoke to another man who they believed was central to the assault investigation, but Mr Anderson said he was not a suspect.
After fleeing Dalmeny St, Ginns drove to an old forestry worker's house in Thompson St and pleaded to borrow a white car. This was the vehicle Ginns used in a high-speed chase and was the car his body was found near.
A man at the Thompson St house, who called himself a "family friend", said the occupants had not seen Ginns for "months and months" until he arrived asking for the car.
He said a 32-year-old who lived at the house had worked "in the bush" with Ginns about 10 years ago. "It [the crime] is nothing to do with him - it's just one of those unfortunate circumstances by association."
