Catherine Campbell murder trial begins watching Garnier interrogation video

The jury inthe murder trial of Christopher Garnierwatched about 2 hours of a9-hour video of his police interrogation following his arrestin the death ofoff-duty officer Catherine Campbell.

RCMP Cpl. Jody Allison testified Monday thathe conducted the interview at the RCMPdetachment in LowerSackville, N.S., on the afternoon of Sept. 16, 2015.

The video shows Garnierdressed in a grey T-shirt and pantsin a plain, windowless room with two chairs, a desk and a computer monitor. For thefirst 20 minutes,Garniersaid virtually nothing, other than to ask if his father had been notified.

Garnieris later seen sobbing and sniffling on the videoas Allison tells him that he's not a bad guy.

"I don't think it was your intention for it to end up the way it did," Allison said.

The Mountie also refers to Garnier's background in occupational health and safetyduring the interrogation.

"The safety-minded people? They are the ones that have a good heart,"Allison said in the video.

During the hours-long interview, Allison tells Garnierhis movements could be tracked by his phone, that police have already interviewed his girlfriend, Brittany, and plays himvideo taken fromoutside the apartment on McCully Street where police allege Campbell was killed.

'How come you snapped?'

He also shows Garnier photos of Campbell when she was alive, and then a picture taken after her body was discovered.

At one point, Allisondescribes the case police are building against Garnier as a "slam dunk" and urges him to talk.

Allison also asked Garnierin the video if he had sex with Campbell. Garnier at first said no. When Allison asked again if he had sex with Campbell, Garniersaid, "I don't think."

"So how come you snapped?" Allison asked. "There has to be some reason."

At the end of the day, the Crown said Garnier's girlfriend, Brittany, was not aware he was being investigated until police woke her up on the morning of Sept. 16, 2015.

The Crown said she wasn't aware Garnier had taken her vehicle, a white Ford Edge, while she was asleep.

Toiletries, passport seized

Garnier, 30,is on trial in Nova Scotia Supreme Court in Halifax for second-degree murder in Campbell's death and for interfering with humanremains. He has pleaded not guilty to both counts.

In earlier testimony today, the jury was told police officers found toiletries, clothes and Garnier'spassport inside a backpack seized from the Ford Edge he was driving when he was arrested.

The court has also heardofficers found a green tarp, yellow rope and a new pair of work gloves in the front passenger seat. Sgt. Andre Habibtestified he photographed everything in the car, without being sure what was significant.

Wearing purple latex gloves, Habibheld up itemsfor the 14-member jury to see Monday, including a hair clip, a strapless dress and a strapless bra all items Campbell was wearing when her body was found.

The Crown alleges Campbell, a 36-year-old constable with the Truro Police Service,and Garniermet in the early hours of Sept. 11, 2015, at the Halifax Alehouse, a downtown bar, and then returned to the McCully Streetapartment.

The Crownhas argued thatGarnierpunched and strangled Campbell in that apartment, putting her body in a green compost bin and dumping it under Halifax's Macdonald Bridge, where she was found several days later.

The jury has heard police combed through the apartment during their investigation into Campbell's disappearance. The mattress for the couch was missing.

Habibtestified police never found the mattress.

The case is scheduled to run until Dec. 21, with a verdict expected just before Christmas.
