Accused in murder of Nova Scotia officer confessed to crime: police affidavit

HALIFAX — An affadavit filed by police in provincial court states that a 28-year-old man accused of killing a Nova Scotia police officer allegedly confessed to being "responsible for her death."

Christopher Calvin Garnier is facing charges of second-degree murder and indecently interfering with a dead body in connection with the death of 36-year-old Catherine Campbell in September.

In a sworn affidavit by RCMP Const. John Berger filed with the court to obtain a warrant for Garnier's DNA, Berger writes that Garnier told two officers he punched Campbell several times in the face and then strangled her.

None of the allegations in the affidavit have been proven in court.

CBC reports that the lawyer for Garnier said police are entitled to their views but the only interest of the Crown and defence is proven facts.

Campbell's body was discovered Sept. 16 near an overpass that leads to the Macdonald Bridge connecting Halifax and Dartmouth, two days after she failed to show up for work with the Truro Police Service.

A preliminary inquiry has been tentatively set for July 11 to 15.
