NT Police Commissioner Reece Kershaw said the five crime scenes were the Palms Motel in Finniss St, the Buff Club in Stuart Park, Gardens Hill Crescent in The Gardens, Jolly St in Woolner and the Coles Express in Daly St.

Commissioner Kershaw said police were investigating whether the man had also tried to enter the Peter McAulay Centre — the NT Police headquarters — in Berrimah.

He said the rampage started about 5.45pm at the Palms Motel.

Witnesses reported hearing multiple gunshots before the shooter — described by police as a caucasian man wearing high-vis workwear — emerged from behind the motel with what looked like a high-powered shotgun.

The alleged gunman is believed to have shot dead one of the victims there and also inflicted the gunshot wounds on the woman.

“First he was shooting on the other side about seven shots, bang, bang and then a close range shot boom,” one witness said.

“Then he came up those stairs and then he went straight for that door and blew up the door about two times and then he had another shot inside.”

Another witness told the NT News she was on the phone to the police when she saw the alleged gunman flee the scene.

“He jumped in a car and he came up the hill and went down to turn around and went flying back down,” they said.

“I was on the phone with the police and I said ‘He’s gone right towards The Gardens’ and I just said that and the cops come and chased him that way.”

Another eye-witness reported seeing a man in high-vis outside the apartment complex with a shotgun.

Yet another witness said she saw a woman shot three times, in both legs, by a man wielding a shotgun.

The woman said she wrapped the victim’s legs in towels while waiting for an ambulance and police.

Police were later seen standing guard outside the Buff Club where one of the victims’ bodies lay dead in the rear car park.

The pub was still open and one drinker told the NT News they earlier saw the alleged shooter involved in a prang outside the venue before speeding off.

“He’s run up the arse of another car but we didn’t really think about it because there was a cop car already here and he’s just sort of ploughed up its butt,” he said.

“A guy got out to have a look at the damage and talk to the driver and the other guy’s reversed out, went around him and straight down the Stuart Hwy.

“All we know is there’s some person shot in the car park, in the back there.”

Another man was found dead inside a home in Jolly St in Woolner.

A witness to that shooting, who did not wish to be named, said he was inside his home watching TV when the alleged shooter broke in with a shotgun in hand and shot his male house mate before escaping.

“He came right in and I asked him what he was doing but he didn’t even look at me, went right past me and shot my mate, he’s still in there,” he said.

“I thought I was dead for sure. It was unbelievable.

Large sections of the city were closed down during the night as police worked to track the suspected gunman.

Police armed with assault rifles and wearing camouflage gear apread out across the city and cordoned off roundabouts and roads in Darwin.
