Fog Blog Nova Scotia Tragedy Log:

On April 18 and 19, 2020, 51-year-old Gabriel Wortman committed multiple shootings and set fires throughout the Canadian province of Nova Scotia. Twenty-two people died and two others were injured before the Royal Canadian Mounted Police (RCMP) shot and killed Wortman at a gas station in Enfield...............

The victims include a 17-year-old, a pregnant healthcare worker and a veteran Royal Canadian Mounted Police (RCMP) officer.

Authorities are yet to determine a motive for the crime. Police say the gunman knew some of the victims.

The gunman, a 51-year-old man, was killed in a confrontation with police.

During the attack he wore an authentic RCMP police uniform and drove a "look-alike" police vehicle, authorities said.

Nova Scotia RCMP updated the death toll from the attack in a statement on Tuesday along with a rough timeline of the events.

Police had previously warned the number of dead could rise as they searched the 16 separate crime scenes across north and central Nova Scotia.

Their work was also slowed by the fact there were a number of fires started - about five, according to police. They had to search through the debris of those badly burnt-out homes for remains.

The full investigation is likely to take months.
