Montreal police announced Friday that they are now investigating the murder of an 81-year-old woman committed nearly a week earlier at a Montreal seniors' residence.

According to our information, the victim was stabbed to death inside the Cité des Retraités N.D.F. seniors' residence, located on rue de Pontoise, in the borough of Rosemont-La Petite-Patrie.

Considering the violence of the crime, it is difficult to understand why it was only during the examination of the body by the coroner that the murder could be brought to light.

According to our information, the body of the octogenarian bore "very obvious" marks of violence, caused by a knife.

It was the Urgences-santé paramedics who discovered the woman unconscious last Saturday evening, around 7:20 p.m., in the residence for the elderly.

The SPVM announced Friday that its investigators are now investigating the 32nd murder to be committed in Montreal since the beginning of the year.

No arrests have yet been made in this case.

Recall that on October 19, another murder was committed in a residence for seniors, in the Vaudreuil-Dorion sector, in Montérégie.

A 90-year-old woman, Annie Dilaurio, was allegedly beaten to death by her 82-year-old husband, Brian Paul Dennison.

The latter has since been formally charged with the unpremeditated murder of his wife.
