A cluster of eight shootings in five days has again left Victoria in the grip of gunslingers, with March set to be the worst month for gun violence since 2014.
The latest shooting happened in Sunshine West, where two men in a black Audi fired shots into a Mazda sedan about 8.30pm on Wednesday.
Two shootings in Melbourne
Police are investigating two drive-by shootings in Melbourne on Wednesday morning.
Two shootings in Melbourne's outer south-east early on Wednesday appear particularly troubling, as one man who was shot in the arm may have been targeted simply for looking "the wrong way" at a passing car, and three adults who had their house hit with four shots in a drive-by attack are believed to be the victims of mistaken identity.
A man was also shot at random when he noticed a car parked with no lights on outside his semi-rural Lara property on Monday night, but the rest of the shootings since Saturday morning followed a more familiar pattern: victims who knew their attackers, and who are often known to police.
It is not clear whether the people involved in Wednesday night's Sunshine West shooting knew each other. Witnesses have told police the Mazda sedan stopped at the intersection of Angus and Bell streets and the black Audi pulled up alongside it.
Two men in the Audi both pulled out handguns and the driver fired shots into the back passenger window of the Mazda, police said. No injuries were reported.
A Fairfax Media analysis has found the apex of the state's gun crime is an area of about 10 square kilometres around Broadmeadows, where 12 shootings have been recorded in less than 15 months.
A third of all the shootings this year have occurred in the area, which is loosely bordered by Sydney, Camp, Pascoe Vale, and Barry roads.
There have been 15 shootings in 10 weeks to start 2016, only one less than in the entire first five months of last year.
The seven shootings in March to date mean it is on track to surpass October last year, when 12 shootings were recorded, as the worst month for gun crime since at least 2014.
It is not believed the two shootings on Wednesday are related, despite occurring 15 minutes apart and in the same region.
There are no obvious links to drugs or outlaw motorcycle gangs.
The first shooting occurred at midnight when a 25-year-old man left his girlfriend's place in Watson Road, Noble Park North, and was shot in the arm.
It is believed he told Armed Crime squad investigators that the shot came from a car driving past that he had seen earlier in the evening.
He said he made eye contact with the driver in the earlier instance and told police he could have "looked at them the wrong way".
The second shooting happened about 15 minutes later in nearby Hallam where the home of a local restaurant owner was shot up.
Police said up to five shots were fired towards the apartment in Frawley Road and four of those shots hit the front windows.
The three adults inside were unhurt. Witnesses heard a car leave.
The latest rash of shootings started with three incidents on Saturday, including the wounding of two men outside the Bros bikie gang clubhouse in Yarraville and the shooting of Mohammad Hassan, who was killed inside a motel in Kingsbury.
