Death toll in Nova Scotia shooting rampage increases to 23

The death toll in the worst shooting in Canadian history has risen to 23 -- one day after authorities said they expected to find more bodies as the investigation into the rampage continued.

Royal Canadian Mounted Police reported Monday that some of the victims in the Nova Scotia shooting were specifically targeted by the suspect, identified by police as 51-year-old Gabriel Wortman, while other victims were randomly killed.

"It appears that some of the victims were known to the suspect and others were targeted and not known to the suspect," RCMP Chief Superintendent Chris Leather said at a press conference Monday in Halifax.

Police on Tuesday said they had found four more bodies, increasing the death toll from 19 to 23. Five properties had fires, and more victims were believed to be in homes that "burned to the ground," Leather said. Police said Tuesday some bodies had been recovered from burned structures.

"That part of the investigation is still very much ongoing, and again, speaks to why we don't have a final total because we expect that to rise in the coming days," Leather said Monday.

It's unclear if officials still expect the death toll to rise.

The rampage started Saturday in the rural town of Portapique. Officers responding to initial calls found several casualties in and outside a home, according to the police. A "chaotic scene" ensued, Leather said.

RCMP Constable Heidi Stevenson, a 23-year veteran of the force, was killed while responding to the reports of an active shooter, the RCMP said.

A search for the suspect went into the morning, and Wortman was arrested Sunday at a gas station in Enfield, Nova Scotia, according to The Associated Press.

Later that day, the RCMP reported that Wortman was dead.

Wortman was wearing what appeared to be a police uniform and drove a vehicle made to appear like a police cruiser, which helped him move around the province undetected, Leather said. Wortman was not employed by the RCMP, police said.

A 17-year-old was among the victims, but everyone else was an adult man or woman, police said.

In a statement, Prime Minister Justin Trudeau said he was "saddened to learn about the senseless violence in Nova Scotia."

"As a country, in moments like these, we come together to support one another. Together we will mourn with the families of the victims, and help them get through this difficult time."

Queen Elizabeth also sent her best wishes on Tuesday, writing, "Prince Philip and I have been deeply saddened by the appalling events in Nova Scotia, and we send our condolences to the families, friends and colleagues of those who have lost their lives."
