York Regional Police have issued a Canada-wide arrest warrant in connection with a shooting at Moka Espresso in Vaughan that left two dead and two seriously injured.

The suspect has been identified as 27-year-old Jason Hay of Mississauga. Police warn that Hay is considered armed and dangerous.

In 2009, Hay was given a seven-year prison sentence for his involvement in the fatal shooting of 23-year-old David Latchana. At sentencing, the judge deemed Hay “beyond any hope of redemption,” calling Latchana’s murder a “public execution” intended to “instill fear” in Mississauga’s Malton community.

Police have been on the hunt for a lone gunman since the deadly shooting near near Islington Ave. and Highway 7 on June 24.

Surveillance footage previously released by police showed a suspect in a mask exiting a black Nissan Versa on the day of the shooting. Further footage, from the day before the double murder, shows a man, with his face clearly visible, appearing to inspect the same plaza that houses the café.

Investigators said they believed the suspect went to the plaza to plan the next day’s attack.

The Nissan Versa, which was a stolen vehicle, has since been recovered.

Vaughan residents Christopher De Simone, 24, and Maria Voci, 47, were found dead when police arrived at the café.

The two surviving victims have been released from hospital.

Police are urging Hay to seek legal counsel and turn himself in to authorities immediately.
