A man dressed in a police uniform has shot dead 16 people, including a police woman, during a 12-hour rampage.

The gunman, identified as Garbriel Wortman, 51, was wearing a police uniform and drove a fake marked police car, but was not employed by Canadian police.

He is believed to have made and fitted dentures, but his high school year book reportedly alluded to his dream of being a police officer.

Heidi Stevenson, a Royal Canadian Mounted Constable, was among the victims. She leaves behind two children and her husband.

Authorities believe the gunman’s first attack was targeted but he later fired at random.

Wortman died during a stand-off with police, with authorities saying officers discharged their firearms. His cause of death has not been officially confirmed.
