RCMP to provide update today on investigation into mass killing in Nova Scotia

RCMP

Nova Scotia RCMP are expected to provide an update today on their investigation into the mass killing in April that claimed the lives of 22 victims.

It's been more than a month since the Mounties have held such a briefing, though the police force did provide an update in a statement on May 11.

Investigators have yet to reveal key details about the shooting rampage.

Among other things, police have offered few details about the weapons the killer used or how he obtained them.

They have said three of the four semi-automatic weapons came from the United States.

Gun control advocates say details about the firearms are important to the discussion surrounding the federal government's move to ban 1,500 military-style assault firearms.
