Police say an Edmonton man shot and killed six adults and two children before taking his own life. This marks the largest mass homicide in the city’s history.

The victims were found in two separate homes on Monday night and Tuesday morning. Police believe the man responsible for the crime was found dead on Tuesday morning in a restaurant Fort Saskatchewan, a nearby city. Family members of the man, who has yet to be named, was “overly emotional” and “depressed,” according to CNN.

CNN reported that Police Chief Rod Knecht called the killings “tragic incidents of domestic violence” in a news conference Tuesday night. He added that the shootings were not gang related, the “senseless murders” were deliberately “targeted” and there is no threat to the “broader public.”

After receiving a gunshot complaint early Monday, police responded to a home in southwest Edmonton. A man had reportedly entered the home and shot a woman with a stolen 9-mm handgun. She was pronounced dead on the scene. Police identified the deceased as 37-year-old Cindy Duong. Neighbors said the woman had three children who lived in the home.

Less than two hours later, a family called the police asking them to check on one of their relatives. They voiced concerns about the relative being suicidal. They went to the man’s home, but no one answered and the police were not given grounds to enter the home. A day later, police reentered the home and found two men, three women, a boy and a girl dead, Chief Knecht said.

Afterward, police responded to a restaurant about 25 miles from Edmonton and found a black SUV that was associated with the first death in Edmonton. Inside, police found a man dead from an apparent suicide gunshot. They blocked off downtown Fort Saskatchewan, which has since been reopened, during the investigation. The Vietnamese restaurant is still covered in police tape and the front windows and door appear to have been smashed.

Police are certain that this man is the shooter. Chief Knecht said that they are not looking for any other suspects.

Autopsies on the suspect and the remaining bodies are scheduled for Thursday. Police have not specified the relationships between the victims, but The Washington Times reported that they are all connected. The five adults were reportedly between ages 25 and 50 and the children were younger than 10 years old. Knecht said that this was the largest mass murder in Edmonton since six were killed in 1956.

Nearby neighbors told reporters that the two-story home in north Edmonton where police found the seven bodies was occupied by a family of five. They thought the family may have been Vietnamese and did not speak English well. Neighbors said that they often heard loud arguing coming from the home, according to the Edmonton Journal.

Edmonton police had run into the suspect prior to this event. Officers said they had visited the home twice before: once earlier this year, and once in November 2012. The man had been arrested on suspicion of sexual assault, domestic violence and making threats.  Knecht said that the suspect had a criminal record dating back to 1987 which included violence-related and drug-related issues.
