Police believe the man was holding the handle of the crossbow through a hole in one end of the box as he pointed it at the victim. He is standing in the front entrance of a home on Bayberry Drive in Mississauga before the video cuts to him running away as the door slams shut.
"She'll be in a recovery phase for the rest of her life", Det. Sgt. Jim Kettles said during a media availability.
"Her life will never be the same".
Upon arrival, a 44-year-old woman was located suffering from life-threatening injuries and was transported to a trauma centre.
"(She) spent several months in hospital", he explained.
They say the woman and the suspect had a short conversation before the man shot her with a crossbow he had hidden inside the box.
'Comments that were made to the victim by the suspect indicate that the victim was targeted and that the suspect may have carried out the attack at the request of another individual. "I can't speak to those at this time", Kettles said.
Peel police say this is the type of crossbow that was used in the shooting.
Police believe the weapon that was used was created to be used by hunters to take down large game such as moose and deer.
Crossbows 500 millimetres or less in length are prohibited by law but there are no licensing restrictions on weapons such as the one purportedly used. Heather Raymore said it appears that the suspect was hired to carry out a hit on the suspect.
Police are also trying to determine how many people may have been involved in planning the attack.
The vehicle is a dark coloured pickup truck and it arrived in the area of the residence minutes before the attack took place and fled the area minutes after.
Investigators said Monday that the motive for the attack is still under investigation, but it's possible that the suspect was targeted and that someone else was involved in the attck.
"If you feel you can identify the person in this video or if you have any other information that may assist in this investigation, please call Peel Regional Police", Ramore said.
'We are confident with assistance from the public and with current facial recognition technology we will bring those responsible for the attack to justice, ' she said.
