Woman admits 'rough-sex' stabbing

WINNIPEG - A Winnipeg university student who nearly stabbed her boyfriend to death during a bizarre act of consensual "knife play" has been spared a jail sentence.
Catherine McCoubrey, 25, was given three years of probation after pleading guilty to assault for the February 2007 incident in central Winnipeg.
The 24-year-old victim received a puncture wound to his heart and was given little chance of survival when he was rushed to hospital. He has since made a full recovery and is fully supporting McCoubrey, court heard.
The couple had been drinking alcohol and were engaged in so-called "rough sex" when the boyfriend asked McCoubrey to carve a heart-shaped symbol onto his chest.
She agreed, but accidentally pushed the knife in too deep.
Defence lawyer John McAmmond said Tuesday the victim introduced his client to "body modification," and they had previously engaged in knife carving.
