MONTREAL -- Two police officers are among four confirmed dead and one person is in custody following a shooting in the eastern Canadian province of New Brunswick, police said on Friday.
Police in the city of Fredericton identified the slain officers as Robb Costello, 45, a 20-year police veteran and father of four, and Sara Burns, 43, who joined the Fredericton Police Force two years ago.
Burns leaves behind her husband and three children, Fredericton police Chief Leanne Fitch said.
Police didn't release the names of the two civilians killed but said they were an adult male and female.
The 48-year-old suspect, a Fredericton resident who has not been identified, is in hospital and being treated for serious injuries, police said.
Police did not release any possible motives for the shooting.

The Royal Canadian Mounted Police (RCMP), Canada's national police force, will be taking over the investigation, Fitch said.
The Serious Incidents Response Team, an independent investigative body in the neighboring province of Nova Scotia, will conduct a separate investigation into the police use of force, Fitch said.
"I couldn't be prouder of the men and women that serve this city and I want to reassure the public that we will continue to do so in the coming days and months and years ahead," Fitch said.
Police said they responded to reports of gunfire at an apartment complex on the 200 block of Brookside Drive in the city's north end at 7:10 a.m. local time Friday.
