The accused’s lawyer told Geelong Magistrates Court on Tuesday that his client had gone days without his medication for schizophrenia and depression.
“It’s his first time in custody. He has no prior criminal history,” lawyer Michael Brugman said.
“What he does have is a diagnosed history of schizophrenia.
“The deceased in this matter is his younger brother.”
Mr Arslanian, 39, sat silently throughout the brief hearing wearing a blue forensic suit and mask.
He was arrested hours earlier at a friend’s home in Leopold after allegedly fleeing the scene of the shooting on foot.
The court heard he had been charged with murder.
Mr Arslanian sat with his head bowed and was remanded to reappear on March 5.
Friends of the 31-year-old have since taken to social media to pay tribute to the popular butcher who had won a string of awards for best Victorian barbecue sausage at his shop Belmont Fine Meats.
“RIP David you were a great bloke and always made my kids smile and feel welcome. You were a kind hearted bloke, going to miss seeing your face at the butchers,” Matthew Wakefield wrote.
Lizzy Lowry described David as a “kind and gentle soul”.
“I was always there for you as you were for me. I will cherish all those moments for the rest of my life,” she wrote.
Paramedics were called to a house on Boundary Road in Whittington on Monday following reports a man had been shot at 7.20pm.
They were unable to revive David Arslanian.
Anyone with information or anyone who may have witnessed the incident is urged to call Crime Stoppers on 1800 333 000.
