(CNN) A woman will be in recovery for the rest of her life after someone posing as a delivery person shot her point-blank with a crossbow.

The attack, which is being investigated as an attempted murder, occurred in November in Mississauga, Ontario, Canada. This week, police released video footage of the suspect at the victim's door in the hope that the person could be identified.

Emergency services responding to a Mississauga residence on November 7, found a 44-year-old woman suffering from life-threatening injuries and transported her to a hospital, police said in a news release Monday.

Investigators have since determined the victim answered her front door and was met with a person holding a large box. After a brief conversation, the suspect shot the woman in the chest using a crossbow that was concealed in the box. The suspect then fled to a dark-colored pickup truck, authorities said.
