Police are searching for a motive after a Cape Breton man was killed during a fight in Calgary on the weekend.

Craig Kelloway, 32, was originally from Glace Bay, N.S. but he moved to Alberta six years ago. He was working as a math and science teacher at David Thompson Middle School in Calgary.

Kelloway had recently moved to the upscale community of Auburn Bay and was attending a neighbourhood barbecue on Saturday when he met another man there for the first time.

He soon went over to the other man's home where, at some point, police say there was an argument just before midnight.

“An altercation later took place between two people and one of the men died as a result,” says Staff Sergeant Doug Andrus with the Calgary Police Service.

Police have confirmed Kelloway died as the result of a stabbing.

Nick Rasberry, 30, was arrested and has since been charged with second-degree murder. He is due in court on Wednesday.

Neighbours describe him as clean-cut and friendly, and to see blood on the footsteps of his home is shocking.

Police say another person was in the home at the time of the incident, but they weren’t in the room.

A cause of death will not be released until an autopsy is complete.

Kelloway was married and had recently become a father. His son is five months old.

Parents of teacher devastated by loss

Kelloway’s parents say they are devastated by the loss of their son who loved his job and loved the city where he worked.

Harvey and Monica Kelloway spoke to CTV on Tuesday.

Harveysays his son was a kind and gentle-hearted soul.

"His passion was in teaching and he loved the students at the school in Calgary."

Monica, fighting back tears, says she was devastated when she lost her baby.

"He was so kind-hearted. He would do anything for you. I can't get over it yet."

They say they had FaceTimed their son and grandson just hours before he died.

Harvey, who is a retired 30-year police veteran, says he was contacted by Calgary police who told him Kelloway had been involved in a fight after a neighbourhood gathering and stabbed in the stomach.

“It was just a family gathering for a barbecue in a neighbourhood, and late at night, the young fellow got in an argument. He got stabbed in the stomach and passed away very quickly,” says Harvey.

Support has been strong for the grieving parents and they say they've received lots of support from the local police and community.

"You couldn't ask for any more."

Marguerite Verbeski, a close friend and neighbour of the family, says she treated Kelloway like “one of her own.”

“Craig was funny, intelligent, a good student. He was a sweetheart,” says Verbeski. “He was like one of my own children. He was just a good kid, athletic. I am just devastated over this.”

Kelloway is being remembered as a wonderful teacher by colleagues and students at David Thompson Middle School.

“He would joke about stuff, but when you needed to talk about stuff, he was there and he always knew what to say,” says former student Devon Southwell.

Students say he had a passion for everything and always got them to do their best.

Flags are at half mast at David Thompson School and grief counselling is being offered to teachers and students who need it.
