One Windsor man has been arrested, and another Windsor man is being sought in connection with a double homicide investigation in Vaughan.
York Regional Police have issued an arrest warrant for Gerard Murray, who’s wanted on two counts of first-degree murder and one count of arson causing property damage.
Investigators have not been able to locate the 48-year-old Murray, who is known to frequent southwestern Ontario, between Windsor and the Greater Toronto Area.
Murray is encouraged to seek legal advice and turn himself in. Investigators are reminding the public that anyone providing assistance to him may be subject to criminal charges.
At 5:30 p.m. on May 13, police were called to a home in Vaughan for a report of shots fired. When officers arrived, two males were located outside of the home suffering from multiple gunshot wounds. Both males succumbed to their injuries and were pronounced deceased.
While police were on scene, additional officers were dispatched to another area after receiving reports that a blue SUV had been abandoned and set on fire. Investigators have confirmed the SUV was used by the suspects leading up to and following the shooting. The vehicle was reported stolen from Toronto.
Investigative efforts led to the identification of three men who were believed to have been occupants in the same SUV.
