Three people were found dead inside a Brampton, Ont., home Sunday morning in what Peel police said may have been a murder-suicide.

Peel Police Const. Fiona Thivierge said the bodies were found at 99 Hinchley Wood Grove after police got a call around 10:40 a.m. from a family member regarding the well-being of a relative at the address.

When police arrived at the scene, they could see one of the victims inside but the person was unresponsive, so they forcefully entered the home.

The person named in the call was among those found dead.

The victims were a 57-year-old woman, a 61-year-old man and a 91-year-old man. Police said all three reside at the home, and that their names will not be released until next of kin are notified.

Thivierge said it is not yet known when the deaths occurred or the relationships of the deceased.

Mohammed Hamid, a neighbour on the street, told CBC News that the same couple has lived in the home for more than 20 years and that they are "amazingly nice."

Hamid said the woman living at the house worked as a teller at a nearby bank, and that the couple have two adult daughters who have since moved away and had children of their own.

The homicide squad was called to the scene and officers canvassed the neighbourhood for any potential information. The coroner arrived at the home shortly after 6 p.m.
