HALIFAX, N.S. —

A teacher, health-care workers and an RCMP officer are among the 22 innocent people who lost their lives on the weekend during a gunman's 12-hour rampage across several Nova Scotia communities.

It was Canada's deadliest mass shooting. Late Tuesday afternoon, the RCMP, which had previously said the death toll was in excess of 19, sent out a news release saying there were 22 victims. Emily Tuck, 17, was the youngest.

The rampage started in Portapique and ended in Enfield on Sunday.

While the RCMP have not released any names other than that of Const. Heidi Stevenson, who died in the line of duty, they are working with the medical examiner's office to identify all of those killed.

But as tributes to the victims are posted by friends and familyon social media, loving portraits have emerged.

Nova Scotia Teachers’ Union president Paul Wozney said McCully’s students, colleagues, friends and family “know her not only as a passionate teacher, but as a shining love in their lives.”

"Ms. McCully was a passionate teacher with a smile that lit up the classroom," Debert Elementary School said in a message sent out to the school's families.

"She will be remembered for her fearless spirit, her kind and generous heart, and her love for her family and students."

A GoFundMe page has been set up for McCully's two children.
