The man behind a fatal shooting in an eastern Canada city, Matthew Vincent Raymond, has been charged with four counts of first-degree murder, the police said on Saturday.
Raymond, 48, opened fire in the sleepy city of Fredericton, New Brunswick early Friday, killing four including two officers.
He was injured and hospitalised in the process, and was charged with four premeditated homicides as he remains in custody pending a court appearance slated for August 27, Fredericton police said in a statement.
Law enforcement officials released the names of the two civilians slain in the shooting: Donald Adam Robichaud, 42, and Bobbie Lee Wright, 32.
On Friday authorities in the provincial capital — about 75 kilometers (45 miles) from the border between Canada and the US state of Maine — had identified the two officers killed as Lawrence Robert Costello, 45, and Sara Mae Helen Burns, 43.
The incident sparked panic in the city as Canada grapples with rising gun violence, leading to a call for a handgun ban in some quarters.
The mass shooting is the second in the province in recent years, and comes only weeks after a man opened fire on July 22 in a bustling Toronto district, killing an 18-year-old woman and a 10-year-old girl while wounding 13 other people.
