New information has emerged from Peel Regional Police regarding Monday's horrendous shooting across the Greater Toronto Area that resulted in the death of two people, including a Toronto Police constable.

It was in the early afternoon when Peel Police indicated a shooting had occurred in Mississauga and that two people were shot.

"The devastating events from Monday, Sept. 12 across Peel and Halton and into Hamilton have resulted in the senseless death of 48-year-old Cst. Andrew Hong, a 22-year veteran of the Toronto Police Service. His family, the Toronto police and may I say our larger police family are continuing to struggle with the loss of Andrew," Peel Chief of Police Nishan Duraiappah told reporters.

In Milton, 33-year-old auto body shop owner father of two Shakeel Ashraf, was also killed hours after Hong.

"There were three more innocent people who were shot for absolutely no reason. One of who continues to fight for for their life while on life-support," said Duraiappah.

He went on to say that some of the first officers who arrived at the Tim Hortons to find Hong deceased were his colleagues. They were all participating in a training session in Mississauga.

"At the time of the incident, Cst. Hong was on his lunch break and had offered to get his colleagues, who he was training with, coffee. This is when the suspect ambushed and shot him at close range."

Further police investigation revealed that the suspect arrived at the Tim Hortons two hours and 15 minutes prior to Hong's arrival. Police confirmed that the suspect did try to disarm Hong and it appears he was targeted specifically as a uniformed officer.

A second victim in Mississauga was rushed to trauma centre. Now police say that person was a victim of carjacking.

"After the murder of Cst. Hong the suspect immediately fled the coffee shop, across the road to an adjacent parking lot, shot and carjacked another victim and stole the vehicle."

That victim is now in stable condition but has suffered extensive life-altering injuries.

We are grateful for the outpouring of support for our fellow fallen officer, Constable Andrew Hong’s family, friends, and co-workers.

After this, the suspect drove to Milton and shot three people, including Ashraf. The suspect continued to flee to Hamilton, where an "interaction" with police there resulted in his death.

The person believed to be responsible for this shooting spree has been identified as 40-year-old Sean Petrie of no-fixed-address.

"Petrie had an extensive criminal record, which includes convictions for assault, armed robbery, carrying a concealed weapon, careless storage of a firearm, possession of a loaded, prohibited or restricted firearm, breach of probation and failure to comply the the recognizance, several property and driving offences and he was slo the subject of a firearms prohibition," said Duraiappah.

Years ago in March 2007, Petrie was deemed as being high-risk to reoffend and placed on the national flagging system for an offence back in 2005. His last offence was in 2015.

Specific details about the incident in Milton revealed that besides Ashraf, the second victim is a 28-year-old International exchange student.

May Constable Andrew Hong rest in peace. A husband, father and hero, he and his loved ones are in my prayers. https://t.co/xbvypSdPQ9

He works at the body shop part-time and is currently on life-support, however, he is not expected to survive, according to Halton Chief Steve Tanner.

The third victim, a 43-year-old male is also an employee at MK and was shot in the leg.

Police confirmed that Petrie did work at MK for a short period of time and did hear rumours of threats,  but have yet to find concrete evidence substantiating them. 

This whole situation ends in Hamilton where an altercation took place between members of both the Hamilton and Halton police services and Petrie.

Since the Special Investigations Unit is involved, no additional details have been released.

Depsite rumours circulating, police said they have found no evidence to suggest Petrie had any gang affiliation at the time of the incident. They could not provide any knowledge to prior connections. 

Details about Hong's funeral will be shared by Toronto Police today. His daughter recently penned a heart-wrenching tribute to him.
