Police seek witnesses of Moran death

Police say they are hopeful of catching two more people believed involved in last week's fatal shooting of Melbourne gangland figure Desmond "Tuppence" Moran.

Members of the anti-gangland Purana Taskforce, who have taken over the investigation, are still hunting a second gunman and a getaway driver.

The squad has set up a caravan near the Ascot Pasta and Deli Cafe where Moran, 60, was shot dead about noon AEST last Monday.

Geoffrey Armour, 43, has been charged with Moran's murder while Moran's sister-in-law Judy Moran and Armour's girlfriend Suzanne Kane have been remanded in custody, each charged with being an accessory after the fact.

The caravan parked on The Parade, Ascot Vale, contains an image of a car believed to be involved in the shooting - a 1989 bluish green Ford Fairlane already seized by police - and clothing worn by two of the offenders.

One image shows a male wearing a dark coloured beanie, black jacket with a single thin white stripe across the chest, blue jeans and runners.

Another image shows a man wearing a dark coloured baseball cap and a blue and grey jacket, blue jeans and runners.

Inspector Bernie Edwards of Purana Taskforce says the investigation is progressing and police have spoken to many witnesses.

"We're reasonably confident," Insp Edwards told reporters on Monday.

"The investigation has progressed and we're very hopeful we'll get to the bottom of it.

"We're still looking for two (offenders).

"One of the people involved, with the black jacket with the white stripe, they were at the scene of where the shooting occurred and we're (also) looking for a third person who drove the getaway car."

He said police wanted to know of any suspicious activity in the Ascot Vale area in the lead-up to the shooting.

"This crime happened around midday, but we're also asking witnesses in the hours leading up to and possibly the days leading up to whether these people may have been doing a bit of surveillance in the lead-up to the shooting," Insp Edwards said.

He stressed witnesses had nothing to fear by coming forward with information.

"We can speak to them and then give them certain advice," he said.

"Any person who has seen anything, no matter how involved or how trivial, if they could just let us know what they did see."
