Police have issued a fresh appeal for information about a drive-by shooting considered a targeted attack on a Murrumbateman house occupied by one of the ACT's most powerful union leaders.
Three shots were fired into the house about 10.30pm on Tuesday, March 12, with one of those bullets narrowly missing secretary of the Construction, Forestry, Mining and Energy Union, Jason O'Mara, who was in the lounge room.
His wife and three teenage daughters were also in the house at the time and police believe more shots were fired into the lower level of the house but didn't enter the house.
Shortly after shots were fired, a vehicle was heard accelerating harshly from the scene.
Police are interested in speaking to the occupants of a white coloured two-door Lexus sedan seen entering the Barton Highway from William Slim Drive in the ACT.
However, no arrests have been made since the shooting andthere are no suspects identified yet, Hume Police District Crime Manager, Detective Chief Inspector Brendan Bernie said.
Strike Force Eager was established in March to investigate the circumstances surrounding the shooting, Chief Inspector Bernie said.
Police know there was at least one occupant of the vehicle but are unsure how many others were involved.
Officers are considering whether a workplace dispute was the motivation for the shooting, Chief Insp Bernie said.
"We don't believe it was a random attack. We do believe it was an issue relating to the occupants of the house. We are looking at his professional life as a line of inquiry," Chief Inspector Bernie said.
"We're seeking anyone in the community that has information and may have been reluctant to speak to police to now speak up.
"Any bits of information could be the vital link to putting the pieces of the puzzle together and making an arrest.
"Our goal is to get the firearm and the person that used the firearm off the streets."
While police said it was a targeted attack, they couldn't confirm whether it was against the family or an individual.
"It was a targeted attack on the premises," Chief Inspector Bernie said.
"This is a very serious incident and it was extremely lucky the male occupant of the home wasn't critically injured or killed."
Police believe the offenders may have conducted surveillance of the premises in the days leading up to the shooting.
Security measures surrounding the Murrumbateman property have been in place since, Chief Inspector Bernie said.
The family and local community have provided strong assistance to the investigation.
"We just need people in the broader community that might have heard or seen something, especially around that vehicle, that might be able to shed some light on who may have been in the area or responsible," Chief Inspector Bernie said.
Police are urging anyone with information about the shooting or vehicle to come forward. Information, which can also be provided anonymously, can be referred to Yass Detectives or Crime Stoppers on 1800 333 000.
