The jury in the second-degree murder trial of Christopher Garnier in Nova Scotia Supreme Court in Halifax watched video Wednesday of some of the last moments in Catherine Campbell's life.

Garnier, 29, is accused of killing Campbell, an off-duty Truro, N.S., police officer, in September 2015. He's also charged with interfering with a dead body. He has pleaded not guilty to both charges.

Campbell's body was found near Halifax's Macdonald Bridge after she failed to report to her job on Sept. 14, 2015.

The video played in court on Wednesday is from multiple security cameras mounted at the Alehouse, a bar in downtown Halifax.

Police had tracked Campbell to the Alehouse as they investigated why she failed to show up for work the Monday after she was last seen alive.

The videos show Campbell and Garnier arriving separately; they had apparently not met one another until that night, the court heard.

Garnier arrived with a couple of other men, but he eventually ends up alone with Campbell and the pair later move to the quieter second floor of the bar.

Halifax RCMP Const. Kyle Doane described to the court what was in the video. At the urging of the defence, Doane described how Campbell had her arms and legs wrapped around Garnier for several minutes as they kissed.

They eventually moved downstairs in the bar. Doorman Bradley Randall testified he had to tell them to "cool it" because their behaviour wasn't appropriate for a public place.

Garnier and Campbell are shown leaving the bar together. The Crown alleges they went to an apartment on McCully Street in central Halifax where Campbell was killed.

Both the Garnier and Campbell families sat silently as the video was played over several minutes in the courtroom. The only sound was the voices of lawyers and witnesses.

Friend's memory fuzzy

Mitch Devoe, a longtime friend of Garnier, was questioned next by the Crown. He said Garnier and his girlfriend, Brittany Francis, broke up on the night of Sept. 10, 2015.

The two longtime friends ended up at Devoe's apartment on McCully Street in central Halifax, smoking marijuana and drinking from a quart bottle of rum, but exactly how much they drank is up for debate.  

Under questioning by Garnier's lawyer, Devoe admitted it could have been almost the entire bottle.

The pair ended up at a bar downtown where they had a beer and some shots.

The next thing Devoe said he remembered was waking up the next morning in the drunk tank at the police station.

Devoe said he had no recollection of how he got there or even going to a second bar, the Alehouse.

About 40 Crown witnesses are expected to be called over the next few weeks. The trial is scheduled to run until Dec. 21.
