VAUGHAN — Shots rang out in a restaurant north of Toronto on Wednesday, leaving two people dead and two others seriously hurt.

Gunshots occurred about 8:18 a.m. in the Moka café and emergency crews found "quite a scene," said York Regional Police Const. Andy Pattenden.

"The information that we have is that a man arrived here and began shooting," he said.

Maria Voci, 47, and Christopher Desimone, 24, were found dead inside the café, located in a strip mall in a busy area of Vaughan. It's not yet known if Voci and Desimone were employees or customers.

The surviving two victims were rushed to hospital, one man with life-threatening injuries. The second man is in stable condition, police said.

Investigators have not said if there were any other customers or employees in the café who were not injured.

Police are looking for a suspect they described as a male with darker skin fleeing the scene on Islington Avenue south of Highway 7 in a dark-coloured compact car, heading southbound on Islington Avenue.

There was a heavy police presence in the area throughout the day Wednesday as officers canvassed for witnesses and looked for video surveillance of the incident.

It was busy at the time of the shooting and investigators have spoken with several people who were at the scene when the incident occurred, Pattenden said.

Police are asking for anyone in the area around the time of the shooting to contact homicide investigators.
