A middle-aged Indian couple was found murdered at their home in Canada's British Columbia province.
Rajwinder Kaur Mann, 62, and Harbir Singh Mann, 67, both retired teachers who moved to Canada from India four years ago, were found dead in their home by their daughter-in-law on Friday.
The police said they were treating it as a homicide until it is proven otherwise.
Surrey police spokesman Roger Morrow said the Integrated Homicide Investigation Team is still working on the case.
"Scenes like this are treated as a homicide until they can be proven to be otherwise," Morrow was quoted as saying by the Vancouver Sun.
Investigators have seized evidence from the house and further forensic examination will follow.
The neighbours said the couple was still living with their son, his wife and two young children at the time of their death and were mostly seen together.
"Investigators have seized evidence from the residence, which has been sent for forensic examination. The results are not expected in the immediate future," the spokesperson said.
