Police in Longueuil are investigating the murder of a 78-year-old woman in the city's Brossard district.

Officers discovered the woman's body in the basement of her home after a friend called police to say she had not heard from her.

Investigators have met with some of the woman's neighbours to see if anyone heard or saw anything unusual.

Longueuil police spokesperson Gaétan Durocher said they plan to speak with more neighbours over the coming days.

Police would not disclose the type of injuries that caused the woman's death. An autopsy will be conducted to determine when and how she died.

It is the first murder in Longueuil this year.
