The assault, which is being investigated as an attempt at murder, occurred in November in Mississauga, Ontario, Canada. This week, the police released video footage of the suspect at the victim's door hoping that the person could be identified.
Emergency services responding to a home in Mississauga on November 7, found a 44-year-old woman suffering from life-threatening injuries and transporting her to a hospital, police said in a press release Monday.
Investigators have then decided that the victim answered his front door and met with a person who contained a large box. After a brief conversation, the suspected woman in the chest shot with an elbow hiding in the box. The suspect then fled to a dark colored pickup truck, the authorities said.
Investigators believe the attack was premeditated and isolated. Comments on the victim at her door also show that the attack was targeted, the division's superintendent Heather Ramore said during a press conference on Monday.
"The victim suffered massive trauma that was both life-threatening and life-changing," Ramore said. "The attack was supposed to end the victim's life."
It is possible that the suspect carried out the attack at the request of someone else, Ramore said.
The weapon used in the attack, Ramore says, "is commonly used by hunters to kill big game, like elk and deer."
The suspect has his right hand in the box and investigators believe the arm was accustomed to triggering the elbow and the fire, peel Regional Police Detective Sergeant Jim Kettles said.
The victim was home alone, but managed to close the door and call 91
The woman spent several months in the hospital and will be in a "recovery phase for the rest of her life," Kettles said.
In the surveillance video, the suspect face is not covered, but the person is wearing a hat and possibly another head guard and a glove. Kettles said the suspect hat and shoes are distinctive and can also help provide clues that lead to his identity.
