A man police want to speak to over the shooting of Daniel O'Shea was captured on CCTV walking away from the Melbourne park where the 41-year-old's body was found.
Police have released images and footage of the man carrying a red and white Coles reusable shopping bag after Mr O'Shea was found dead at Fawkner Park in South Yarra on April 26.
It is believed he was shot and killed some time about 7.40pm.
Two guns were found about 50 metres from his body.
Detectives have conducted an extensive canvas for CCTV footage throughout the area and have been able to obtain vision of a man they are looking to identify as part of their investigations.
A man dressed in black wearing a green cap was caught on multiple CCTV cameras calmly walking east from Fawkner Park along Toorak Rd, according to police.
Homicide Squad officer-in-charge Detective Inspector Andrew Stamper said there was no doubt there were people in the community who can help solve this investigation.
“Someone out there knows exactly who this man is,” he said.
“They know who he is, why he was there and what connection he has to our victim.
“What we need from those people is a name.
“I understand that there are people, especially those with connections in the criminal underworld, who feel they don’t want to get involved in these incidents.
“But regardless of the circumstances, someone has been murdered. We have a mother who has lost a son, people have lost a partner or a friend.”
Anyone who saw the man, who was wearing a distinctive green cap, walking in the area on the night is also asked to come forward.
Anyone with any information is urged to contact Crime Stoppers on 1800 333.
