Another man was taken to the hospital with unknown injuries.
Shortly after 1 p.m., HRPS was called to a shopping plaza on Plains Road East in relation to a shooting.
In April 2019, Musitano was critically injured after he was shot at a parking lot in Mississauga while leaving his lawyer's office. Upon arrival, HRPS discovered two people suffering from gunshot wounds.
The motive for the shooting is unclear and it was not immediately known if it was connected in any way to Pat Musitano's killing. "He's been a marked man and has been finished as an effective 'Ndrangheta cell leader in Hamilton and the GTA for some time".
In may 2017 his younger brother Angelo Musitano was gunned down in his pick-up truck as he pulled into the driveway of his Waterdown in broad daylight. Angelo Musitano was shot and killed in the driveway of his own home just weeks before that.
Pat Musitano's house was sprayed by bullets two weeks later.
Speaking at the scene of the shooting just before 4 p.m., Const. Ryan Anderson with Halton Regional Police told reporters officers are searching for a male suspect who fled the area westbound on Plains Road East in a newer model grey four-door sedan with a sunroof, similar to an Infiniti Q50.
According to investigators, the suspect vehicle would have "fresh damage to the driver's side in the area of the doors".
A plea bargain allowed the brothers to plead guilty to the lesser offence of conspiracy to commit murder in the shooting death of Niagara crime boss Carmen Barillaro in 1997.
No further suspect description has been provided by officials thus far. Pat and Angelo were sentenced to 10 years in prison in 2006 but they were released in 2006. They also warned that residents and businesses should expect a "heavy police presence" in the area as they appeal for witnesses to come forward with information.
