EDMONTON — Police say the recent mass murder of eight people in Edmonton underlines the need for public awareness of domestic violence.

Staff Sgt. Sean Armstrong with the domestic offender crimes section says family abuse is society’s responsibility.

He says there are many agencies that offer help for victims, if they want it.

Phu Lam shot seven people in his home on Dec. 28, including his wife, eight-year-old son and three-year-old niece.

The next day he shot and killed a woman in another house where he was looking for someone else, then killed himself.

Court records show Lam’s wife told police two years ago and he had threatened to kill her and her family, but she later recanted her story.
