Halifax jury hears from friend of man accused of killing Kristin Johnston

A Halifax jury has heard that Nicholas Butcher appeared "upset" about his relationship with Kristin Johnston the night before the Montreal-born yoga instructor was found dead in her home.

Adam Chisholm told Butcher's second-degree murder trial that the 35-year-old man came over to his place on the evening of March 25, 2016, with Johnston's pit bull Charley.

The jury has heard Johnston was with friends at a Halifax bar that same night, and that Butcher was staying at her home on Halifax's outskirts at the time of her death.

Chisholm says Butcher appeared "upset" when he arrived, and gave him a big hug, and throughout the evening they talked about his relationship with Johnston and how he felt she had been distancing herself from him.

Chisholm says as the night went on, Butcher's mood lightened.

He says they had been drinking, so the plan was for Butcher to stay the night.

Chisholm says he woke up on the couch at dawn on March 26, 2016, and Butcher was gone, but Johnston's dog Charley was asleep on his spare bed.

The Crown alleges that Butcher killed the 32-year-old Johnston and tried to kill himself at her home in Purcells Cove that same morning.

Prosecutor Tanya Carter has said the medical examiner will testify that Johnston had 10 wounds on her neck, and that her death was caused by sharp force.

Butcher has pleaded not guilty.
