Police and RCMP officers survey the area of a shooting in Fredericton, N.B. on Friday, August 10, 2018.

A New Brunswick judge has lifted a publication ban on court documents in the Fredericton shooting that killed four people, revealing details about how the deadly attack unfolded.

The province's Court of Queen's Bench had issued the ban on Monday — hours after media reported on their content — imposing an information blackout on the sequence of events that claimed the lives of Bobbie Lee Wright, Donnie Robichaud and Fredericton police constables Robb Costello and Sara Burns.

Court documents unsealed Friday revealed the alleged gunman was wounded in the abdomen as he allegedly engaged another officer from his apartment window.

The Crown information sheet says around 7:20 a.m. last Friday, a woman called 911 to report shots fired at 237 Brookside Drive.

The documents say the woman said someone was on the ground and she wasn't sure if they were alive.

Upon arrival, Costello and Burns went into the driveway while another officer who arrived moments after, Sgt. Jason Forward, stopped to ask questions of a passerby.

"Sgt. Forward then heard a couple more gunshots so he proceeded into 237 Brookside Drive in back of building C," the documents state.

"Once there, he noticed Constables Costello and Burns laying on the ground not moving. He also noticed another male on the ground and not moving, beside Const. Costello."

A male witness told Forward that shots were coming from the top floor of the apartment building. He and another officer then entered the building, set up containment and confirmed the alleged shooter was in Apartment 11-C.

Forward later learned that another officer, described in the documents as Const. Arbeau, had engaged the shooter after he saw him point his long gun at him from the window.

"Const. Arbeau believed he had hit the shooter in the torso," the documents say.

"A little while later members of the (Fredericton Police Force Emergency Response Team) entered the apartment and took the lone occupant and shooter into custody. The suspect had been shot in the abdomen."

Police found "items believed to be firearm(s) and ammunition" inside the apartment.

Police say in the document that Wright's body was found in the passenger side of a vehicle — which was registered to Wright — and all four victims were found in and around the vehicle.

The vehicle's windshield had been blown out.

Police say Costello, Robichaud and Wright were pronounced dead at the scene while Burns was taken to hospital, where she was pronounced dead.

Matthew Vincent Raymond, 48, has been charged with four counts of first-degree murder. He is set to appear in court on Aug. 27.

Several media organizations had challenged in publication ban in court, and arguments were made earlier this week.

In handing down her decision Friday, Justice Judy Clendening said "the evidence falls short of establishing a ban."

Prosecutor Cameron Gunn had told the court that the Crown was prepared to lift the blanket publication ban, but an amended order seeking a more "narrow ban'' had been filed instead. That ban would have unsealed the documents but continue to block the publication of names of individuals who have not spoken with media yet.

But David Coles, a lawyer representing several media outlets, argued there was no basis for sealing the identities of individuals named in the court documents. He said the names would be in the public domain during the trial, and that reporters could learn the names from other sources.
