Two petrol attendants were killed in Bishop Lavis early on Friday morning and two other employees were injured.
A teenager was killed on Thursday in the area in what has been reported as a hit.
Bishop Lavis Community Policing Forum chair Graham Lindhorst talks to John Maytham about the incidents.
He says they are not sure if the killings are linked.
There is speculation that the attack is related to the owner of the petrol station being gang connected.
That filling station is owned by Ralph Stanfield, and we know what his history is and what he is involved in.— Graham Lindhorst, Bishop Lavis CPF chair
There have been a number of other murders nearby in recent times, he says.
Some community members would say there is a war going on in the area at the moment.— Graham Lindhorst, Bishop Lavis CPF chair
He says the community does bring information to the police which assists them to make arrests, though at times people are afraid to talk.
