Verdict expected in trial of Calgary man who fatally stabbed neighbour

CALGARY — A verdict is expected today in the trial of a man who admits stabbing his new neighbour 37 times but says the killing was a case of self-defence.

Nicolas Rasberry, 32, is charged with second-degree murder in the death of Craig Kelloway, 31.

During the trial, court heard that Rasberry told police Kelloway had threatened to sexually assault both him and his wife.

The prosecution argued Rasberry, who didn't testify during the trial, has not sufficiently explained why he needed to use three knives or why the attack was so vicious.

The two men and their wives met for the first time on the day Kelloway was killed, getting together as new neighbours for a few drinks and a barbecue.

Later that night, Rasberry made a call to 911, saying he'd stabbed Kelloway and telling the operator that Kelloway had tried to have sex with him after their wives had gone to bed.

Rasberry told investigators he felt like he had to "put him down," but said the last thing he wanted was for Kelloway to die.

During the trial, the medical examiner said that Kelloway was stabbed 37 times and his chest cavity, lungs, ribs, intestine, and diaphragm were punctured in the attack.

The expert said the incident was so violent that knife fragments, including the tip, were left in Kelloway's body.
