TORONTO — Canadian police charged a man Saturday for the deaths of two police officers and two civilians in a shooting that struck a nerve in a country that has been roiled in recent months by several instances of mass violence.
Police in the eastern city of Fredericton, New Brunswick said that Matthew Vincent Raymond, 48, was arrested and charged with four counts of first-degree murder.
Horizon Health, which delivers care for New Brunswick's Department of Health, said that Raymond was the only person being treated for injuries related to the shooting. He is due to appear in court August 27.
The victims have been identified as police Const. Robb Costello, 45, police Const. Sara Burns, 43, Donnie Robichaud, 42, and Bobbie-Lee Wright, 32.
Robichaud and Wright were in a relationship, according to Facebook and Robichaud's cousin, Sean Callahan, who said they had just gotten together at the beginning of August.
No motive has been disclosed, and police said they were working to determine a link between the gunman and the couple.
Police said Costello and Burns were responding to calls of shots fired at an apartment complex and saw two deceased civilians before being shot and killed themselves.
Fredericton police ChiefLeanne Fitch said Raymond used a long gun and was in an elevated position when he fired. Fitch said he was shot by police and was in serious but stable condition.
Judith Aguilar, an office manager for Sunfield Apartment Rentals, said Raymond lived in the complex for about four months and was an avid cyclist who often came to pay his rent in cash while wearing a bike helmet.
"He seemed like a very normal and pleasant person, really," she said. "He's tall and was in fairly good shape because he biked everywhere."
At one point, she said maintenance workers needed to do some work in his apartment and he didn't want the workers there while he wasn't present.
"He seemed concerned, he said he had an expensive computer and an expensive bike," she said. "They didn't even have to go all the way into the apartment, they were just fixing his doorframe at the time."
Residents were stunned by the episode, which took place in a city of 60,000 that last saw a homicide in 2014.
But the shooting comes as Canada wrestles with a string of violence, including an instance in Toronto last month where a man with a handgun opened fire in a crowded part of the city, killing two people and wounding 13 before he died in the confrontation.
In April, a man who linked himself to a misogynistic online community used a van to run down pedestrians in a busy part of Toronto, killing 10 people and injuring 14.
Authorities are also still pursuing leads in an ongoing investigation of a serial killer who has been charged with killing eight men in the city in recent years.
In 2014, a shooting in Moncton, New Brunswick left three Royal Canadian Mounted Police officers dead and two wounded.
