"Of the five firearms found in the gunman’s possession on April 19, three were obtained illegally from the United States; one was obtained illegally in Canada through the estate of a deceased associate of the gunman," Campbell said on Thursday.
The fifth firearm was taken from 23-year RCMP veteran Heidi Stevenson, after the shooter, identified as Gabriel Wortman, killed her.
Wortman wore a police uniform and used a mock RCMP cruiser to embark on a shooting spree after assaulting a former female partner. The shooting left 22 victims dead and is the deadliest firearms-induced tragedy in Canadian history.
Canada’s federal police agency confirmed that the investigation into the firearms offenses is still in the active phase and that RCMP is coordinating with domestic and international counterparts.
Campbell added that the RCMP is still looking into the origin of the authentic police uniform the 51-year-old gunman used during the deadly assault.
The RCMP confirmed that the gunman did not use the mock RCMP vehicle in his possession to pull over other drivers during the attack, as was erroneously reported earlier.
