The gun Comanchero bikies used to murder Mitat Rasimi was allegedly supplied by a criminal who was shot dead a month later.

A star witness in the Rasimi murder trial told investigators that veteran gangland figure Daniel O’Shea was the original source of the murder weapon.

O’Shea – known in underworld circles as “Shot Caller” – allegedly had strong links to the feared outlaw motorcycle gang.

Witness A told the ­Supreme Court trial over Rasimi’s killing murder that O’Shea had given the gun to the bikies.

Rasimi – once a player in Tony Mokbel’s drug empire – was shot dead in an ambush by Comancheros Laiseni ­Kakato, 31, and Richard Ene, 29, in March, 2019.

Mitat Rasimi was gunned down as he sat in his car on a Dandenong street.

The bikies pounced as Rasimi sat in his car on Dawn Ave, Dandenong.

Then, 54 days later, it was O’Shea’s turn when he was ­fatally shot in Fawkner Park, South Yarra. Jason Milhuisen has been found guilty of the murder of O’Shea after a ­Supreme Court jury trial which ended last week.

Milhuisen lay in wait ­behind trees and opened fire on O’Shea, before allegedly rolling him over and shooting his face so he could not have an open-casket funeral.

O’Shea, 41, was mentioned in other contexts during the Rasimi trial.

His name came up with others in what was described as the “narrative” around the attempted murder of veteran crime figure Mohammed Keshtiar, known widely as “Afghan Ali”.

A witness told a court it was Daniel O’Shea who provided the gun used to kill Rasimi.

Keshtiar was murdered at South Yarra last year in a killing suspected of being linked to Melbourne’s fiery gang conflict for control of the illicit tobacco market.

Allegations were also made by a key Rasimi trial prosecution witness who testified about Comanchero activities that O’Shea had been sent to rob a drug dealer.

The Rasimi and O’Shea ­investigations were among the most complex gangland murder investigations ever undertaken by Victoria Police’s homicide squad.

They involved bringing on board a number of crucial ­witnesses with intricate knowledge of Comanchero criminal activities.

Some of the most significant names in Melbourne’s underworld came across the radar of investigators during the inquiries.
