UPDATE: Charges Laid In Fredericton Shooting

Fredericton Police say Matthew Vincent Raymond has been charged with four counts of first-degree murder in the shooting deaths of two police officers and two civilians.

Police say the 48-year-old Fredericton man is accused of killing Bobbie Lee Wright, Donnie Robichaud and Constables Robb Costello and Sara Burns in the Friday morning shooting.

They have not said whether he knew any of the deceased.

As of Saturday morning, the residential area where the incident took place remains cordoned off and a mobile police command post was on scene.

An officer said it was unclear how long the probe would take, and police have asked anyone who captured photos or video of the incident to come forward.

A local hospital was also treating multiple victims, but police won't say how many people were injured in the incident.

Fredericton Police responded to the Brookside Dr. area on the city's north side Friday just after 7am local time for a report of shots fired.

The investigation has since been turned over to the RCMP.
