RCMP are reporting one suspect is in custody related to an early morning shooting that left four people dead in Fredericton, New Brunswick.
The Winnipeg native, who lives immediately off Brookside, said residents have been advised to stay inside with their doors locked.
"I looked out the window and there were three police cars on the street just across from where I live", said another witness in the area.
Fredericton Police officer Robb Costello.
Genine Patricia Paul-Dimitracopoulos met Constable Costello almost 15 years ago in her role as a social worker with St. Mary's Child and Family Services.
Earlier on Friday, Fredericton police said that two of those killed were police officers.
He said: "You hear a lot about gun violence in the United States, but what's starting to sink in is that those noises were people losing their lives".
Jackie McLean says a police inspector told the family this morning that her common-law partner was among the four people who died in the incident. More information will be available when we can confirm'.
Fredericton Deputy Police Chief Martin Gaudet told reporters the two officers killed were responding to an emergency call about gunshots.
"But it started before then", she said.
There were between six and 11 homicides a year in New Brunswick between 2012 and 2016, according to Statistics Canada. They say they are prepared to receive any victims and help the community in any way needed.
Gaudet said police entered the shooter's apartment in the residential area of the city north of downtown, and arrested a 48-year-old man.
For some, the terror began from the moment they opened their eyes.
Two police officers were among four people killed Friday in a shooting that sparked panic and a police lockdown in a sleepy town in eastern Canada.
The shooting occurred in the Brookside Drive area of the city of about 60,000 people, police said.
It took place around 7 a.m. local time. "In this time of shock and grief, let us all protect their families", Fredericton's mayor, Mike O'Brien, said on Twitter.
Residents of the Brookside neighborhood of Fredericton, New Brunswick reported waking to the sounds of multiple gunshots.
