Police accused a man of the death of four people, including two policemen, and identified civilians killed in a gun battle on Friday in the city of Fredericton, eastern Canada.
Police accused Matthew Vincent Raymond, 48, of four counts of first-degree murder, according to a statement on Saturday. They identified civilian victims as Bobbie-Lee Wright, 32, and Donald Adam Robichaud, 42.
The police did not disclose information about a possible motive or weapon.
The four people killed, including the police Sara Mae Burns, 43, and Lawrence Robb Costello, 45, were shot dead in an apartment complex in Fredericton, capital of the province of New Brunswick.
Police said officers responded to a report of gunfire early Friday morning and found two civilian casualties on the ground.
Sean Callahan said he grew up with one of the victims, his cousin Donald Robichaud, in rural New Brunswick. Robichaud, a musician and father of three, had recently started a new relationship with Wright, Callahan said.
"Donnie is probably the best person you can meet in your entire life, the nicest person," Callahan said by phone from Fredericton.
"Who the hell would want to kill Donnie Robichaud?"
According to his Facebook pages, a Fredericton man named Donnie Robichaud was in a relationship with Bobbie-Lee Wright.
The police officers killed were Burns, who had served two years in the force and two others as an auxiliary officer, and who had three children; and Costello, a 20-year veteran who left behind four children.
Friday's shooting was the latest explosion of armed violence across the country. Arms laws in Canada are stricter than in the United States, but the proliferation of weapons has led to an increase in gun-related crimes in recent years.
The shooting occurred three weeks after an armed man walked down a busy Toronto street, killing two people and wounding 13 before committing suicide.
