Jonathan Dick remains at large a month after younger brother David, 36, was brutally attacked in a carpark at Westfield Doncaster.

Police have found a car containing a sword, believed to have been used in the murder, but there has been no sign of Jonathan.

It’s believed he might be running short of money and visiting soup vans and homeless shelters for food.

Mother Carol Cloke said in a statement she and youngest son Simon were desperate for news that Jonathan, who has mental health issues, was safe.

“I would like to say to Jonathan that I miss my Sunday chats with him, could he please try to call me in any way he can,” she said.

“I love him and want him to feel he can connect with me in any way possible even though it may have to be via the police force.

“Jono, you are my son and I love and miss you so.”

The men’s uncle John Hird, speaking on behalf of the family, said: “We have already lost one loved one - please do not let us lose another.

“Please surrender yourself to police so that the family can know that you are safe and they can assist you in any way.

“Everyone in the family is extremely concerned with your welfare and your health so we are all pleading with you to give yourself up.

“We will all help you in any way possible.

“You are not alone.”

Asked about the family’s reaction to CCTV showing Jonathan carrying a sword at the major shopping centre before the attack, Mr Hird said: “It was totally unbelievable.

“We had seen similar CCTV footage that the police had asked us to view a couple of days earlier and I had no idea. I had a person in mind that I thought might have been the person so maybe I was looking to try and find that that person’s face was the face.

“I had not even comprehended nor did anyone else that it was Jonathan.

“When that came to light and I saw the footage - I was shattered.”

He said Jonathan had even driven his brother home after sharing Christmas dinner and had appeared to be his normal self.

Homicide Squad investigators today released footage of Jonathan withdrawing $100 from a bank branch in Melbourne’s northern suburbs, which he often visited while working as a plasterer.

The vision, taken on January 18 - before David’s February 3 death - isn’t related to the case but it’s hoped it gives a clear image of what Jonathan looks like.

The 39-year-old, from Seymour, withdrew $200 from an ATM two days before his brother’s death and hasn’t touched it since.

Detective Sen-Sgt Julian Horan said the account had limited funds and it was likely Jonathan was running short on cash.

He do not have his mobile phone.

“Despite exhaustive inquiries we have made we are no closer to identifying Jonathan’s whereabouts or where he may be headed,’’ Det Sen-Sgt Horan said.

“We don’t believe he has great financial means to support himself.

“This leads us to believe that he may attend at homeless shelters and soup kitchens in the metropolitan or regional areas to sustain himself.

“We want to catch up with him sooner rather than later.”

Jonathan was last seen walking south on Wamba Rd in Ivanhoe East shortly after his brother’s death.

CCTV shows him carrying a backpack and putting on a light coloured hat.

His blue 1997 Ford Fairmont sedan was found in the street at about noon on February 11 with a sword believed to be the same one used to attack David inside.

Jonathan is Caucasian, 180cm with short grey hair and a solid build.

He has a wolverine v sabre-tooth tiger tattoo on his right thigh to his knee and another tattoo on one of his calves.

He may be carrying a knife and the public is urged not to approach him.
