An Indian-origin couple and their teenage daughter were killed in a "suspicious" fire which tore through their home last week in Canada`s Ontario province, police said on Friday. A fire engulfed a home at the Big Sky Way and Van Kirk Drive area of Brampton on March 7, a press release by the Peel Police said.

After the blaze was put out, investigators located what was believed to be human remains within the gutted house, but the number of people killed couldn`t be ascertained at the time.
