It is now known 19 people have been been killed by a gunman in Nova Scotia in Canada who disguised himself as a police officer.
It's Canada's deadliest mass shooting.
The Canadian police have found 16 crime scenes so far, but warn the death toll could still rise.
The Prime Minister, Justin Trudeau, says the shooting spree happened in small towns, where people have deep roots, they know their neighbours and look out for one another.
The 12-hour rampage started late on Saturday and ended when the gunman was killed in a confrontation with police. Canada correspondent Laura McQuillan has been following the story.
