CCTV Of Bloody, Shirtless Darwin Shooter During Alleged Rampage

Ben Hoffman has been charged with four counts of murder over an alleged mass shooting in Darwin.

Hoffman allegedly purchased weapons for the deadly escapade on the morning of June 4, and had been pulled over by police for speeding just hours before the alleged shooting attack.

Police said they were unable to name the store where the knife and ammunition were allegedly purchased.

"There was a knife and the ammunition used that had we believe is linked to the firearm were purchased together locally in Darwin on the morning of the offending," Police Commissioner Reece Kershaw said on Thursday.

"We also believe that at the time of the offending he was displaying behaviors consistent with being under the influence of an intoxicating substance and we're awaiting toxicology results."

Police also revealed on Thursday that officers had spoken to Hoffman on the day of the shooting, after pulling him over for speeding.

He was stopped at 10.52 am on the Arnhem highway at Humpty Doo for allegedly driving 94 km/h in an 80km/h zone.

Hoffman was driving a silver Proton with NT registration CD49OU, a vehicle the police seized following the shootings.

When asked by police why he was speeding, he apparently told them he was test-driving his car.

Hoffman's vehicle was picked up by police radars in a further two instances that same day. Once at 11.03am in Coolaigna and at 12.12 pm on Stewart Highway.

At about 4pm, Hoffman went to a home on Geofferys Road, however, police were unable to confirm the purpose of his visit. Police were called to that home by a member of the public after Hoffman left at about 5.20pm on Tuesday.

Police spoke to a number of residents in the area, and by the time the visit had concluded, the shooting had already started in Darwin city centre.

Harrowing CCTV images capture the moments before and after the alleged murder of Rob Courtney.

In one image, Hoffman can be seen strolling into the Woolner residence armed with a shotgun and wearing a high-vis shirt.

Four minutes later, he can be seen leaving, this time shirtless and covered in blood -- holding a gun in one hand and a knife in the other.

Courtney, a casino security guard, fought back at his alleged killer. In the tussle, the 52-year-old took the gunman's own knife and stabbed him.

Four people were killed and a 23-year-old woman injured during the shooting spree. Police said on Wednesday Hoffman was looking for someone called 'Alex'.
