In the hours before a love-sick Darwin man allegedly gunned down four people, he paid a visit to his estranged girlfriend's home armed with a hammer, his trial has heard.
Benjamin Glenn Hoffmann has pleaded not guilty to four counts of murder in less than an hour at four locations in the afternoon of June 4, 2019.
In the early hours of the morning before, the 47-year-old drove to a woman's home in Darwin's outskirts with mate, Mihalis Makrylos.
"He parked outside the premises ... She had a torch on her and I could see her blonde hair," Mr Makrylos told the Northern Territory Supreme Court on Wednesday.
Hoffmann spoke to the woman for about 10 minutes while Mr Makrylos waited by the car smoking.
"After he finished talking to the girl he came into the vehicle, that's when he gave me the hammer," he said.
"I never knew the whole time that he had a hammer on him."
Mr Makrylos said Hoffmann had consumed crystal methamphetamine as the pair drove at speeds of up to 180km/h to the woman's home.
"I asked him to slow down but he wouldn't listen to me," he said.
"I feared for my life."
Hoffmann's ex-girlfriend, Kelly Collins, has previously told the court that she and Hoffmann smoked ice at her home earlier the same night.
She said he smoked "quite a bit, as in three pipes" in about an hour then left before returning later in the evening.
"He tried to coerce me to go with him," she said of Hoffmann's late-night visit.
"I ran to (my neighbour). I said 'We have to ring the police'."
Two weeks earlier, Ms Collins, sent Hoffmann a text message saying she was in love with another man.
"Hoffy, I love Alex," she wrote on May 20.
Hoffmann initially responded with a series of humorous texts but in the days after, his demeanour changed and he repeatedly told workmates he was going to "blow (Alex's) head off".
After the visit to Ms Collins, Mr Makrylos drove with Hoffmann to Royal Darwin Hospital.
"The nurse had called him in (and) he called me over and told me I had to walk home," Mr Makrylos said.
"He said to me 'if any police or anyone says anything, tell them I'm delusional'."
Asked if Hoffmann said he was actually feeling delusional, Mr Makrylos said "no".
Hoffmann told hospital staff that his drink had been spiked, and asked them to take a blood test and provide an antidote.
But tests found no evidence he'd been poisoned and a doctor told him to go home.
The Crown says Hoffmann's first victim, Hassan Baydoun, 33, died about 5.38pm at a motel the same day.
Hoffman then allegedly shot Nigel Hellings, 75, at an apartment block and Michael Sisois, 57, in a car park.
Rob Courtney, 52, was stabbed more than 30 times and shot dead at an industrial yard.
Prosecutor Lloyd Babb SC has said Hoffmann was searching for Ms Collins and Alex Deligiannis at the time.
After the killings, Hoffmann told police he believed he'd been poisoned the night before.
He said it caused him to be "out of his mind" and temporarily insane.
But the court heard police pulled Hoffmann's car over for travelling 14km over the speed limit about 11am after he left the hospital.
Dressed in hi-vis, Hoffmann was "polite and respectful" to Senior Constable Scott Aiken, body-worn camera footage played to the court showed.
Const Aiken told the court he didn't see anything that indicated Hoffmann was under the influence of alcohol or drugs.
Former mate, John Rorvik, said that in the weeks before the shooting, Hoffmann asked him to "get him a gun".
"I said 'I'll try' but I didn't have any intention of doing it," he said.
Mr Rorvik said Hoffmann also came to his home on the day of the shootings and "gave us the keys to his car and said we could have it".
The trial continues Thursday.
