Swanbourne murder victim David Liam Johnson was hit by a car before being taken to a park and shot, police said this morning.
Major Crime Squad Det. Sgt Graeme Johnston said police were still "struggling to find a motive" for the March 8 killing, but the 32-year-old's post mortem had shed some new light on the incident.
Det. Sgt Johnson said police now believed Mr Johnson was struck by a motor vehicle and a short time later driven to Lime Kiln Field, a small park not far from Swanbourne beach.
He was fatally shot in the head at the suburban park about 11.20pm.
Police are keen for members of the public to recall events on that Friday night. The car hit Mr Johnson "at an unknown location" so anyone who heard anything unusual on the night of March 8 should contact Crime Stoppers on 1800 333 000.
"We’re seeking anyone with any information in relation to the murder of Mr Johnson and we’re also seeking anyone with information or that may have witnessed him being struck by a vehicle," Det. Sgt Johnston said. "Unfortunately we don’t know where it has occurred and that’s why we’re obviously seeking any information from the public.
"We would anticipate that it occurred sometime shortly before he was taken to Lime Kiln Field and shot.
"The feedback and the info coming in from the public has been very good and we’re very happy with the amount of information coming in.
"But we are struggling to find somebody with a motive to have done this to Mr Johnson. The indications are from everyone that we’ve spoken to that he was a generous and kind person so it’s definitely one of the things that we’re trying to identify."
Police are still scouring CCTV footage from homes around the park.
Earlier this week, Mr Johnson's sister Ele and aunty Jennifer, who did not want their surnames published, spoke of their shock , disbelief and devastation.
“He was much loved, he was a bit of a larrikin and a free spirit who was up for any adventure,” Ele said. “He was a big family man, always focussing on his family and helping them as much as he could.”
