The PhD student and taxi driver who was one of four men shot dead in a violent and apparently random rampage in Darwin, had never met the accused gunman, his cousin says.
Hassan Baydoun had been driving his taxi but returned home to his studio apartment in McMinn St on Tuesday evening for a meal break.
In what appears to be a tragic case of bad timing, he was there at the time the gunman was going from room to room inside the building, firing his gun and shouting the name of a man - 'Alex' - according to witness Matthew James.
Mr Baydoun, 33, moved to Darwin from Lebanon 10 years ago, his cousin and fellow Darwin resident Abdallah Salman told AAP.
He had completed a bachelors as well as a masters degree in IT and was taking a break before starting his PhD.
"He was a lovely person, he had a good heart. He was a very easy going person who was always smiling, a very happy person who didn't have any enemies and his friends loved him," Mr Salman told AAP.
"As we know now he was accidentally caught up in this, I have no idea but it looks like it was a random shooting.
"I don't think he knows the guy or anything. The guy was looking for someone called 'Alex' and he just got the wrong people."
Mr James told AAP the woman he helped after she was shot in the same building was also saying she had not met the gunman. She was saying :"I've been shot, I don't know why, I don't have anything to do with anything".
Darwin man Ben Hoffmann, 45, was dragged from a ute, tasered and arrested by police about 100 metres from where Mr Baydoun was shot dead.
A group of about a dozen distraught men who were friends and relatives, including Mr Salman, gathered after the shooting outside the Palms Hotel where Mr Baydoun lived, with many in tears.
Mr Baydoun's two brothers used to live in Darwin but returned to Lebanon where his parents live.
His cousin, Haidar Baydoun, posted in Arabic on Facebook "God has mercy on you, cousin".
Ali Malik wrote "very sorry for your loss brother, he had nothing but smiles every time I spoke to him".
The Islamic Society of Darwin held a prayer service on Wednesday for Mr Baydoun.
The Blue Taxi Company said he was a beloved driver.
"Our Company is heartbroken and his colleagues are in a state of shock," a statement said.
"Someone shot having a meal break while going about their own business."
