Police Chief Rick Hanson confirmed the suspect arrested in what he called the "worst mass murder in Calgary's history" is the son of a veteran Calgary police officer.
Hanson said the suspect in the five stabbing deaths was an invited guest at the party. The man arrived at the home, "obtained a large knife" and began attacking individuals at the party.
Four men and a woman were killed -- three men were found dead when police arrived, while two others, a man and a woman succumbed to their injuries in hospital.A person determined to kill doesn't need a gun to do a lot of damage. If you have strangers in our house, it might be good to make sure that nothing dangerous is within reach. If you are at the point where you have to carry a gun in your home, reconsider your guest list.
