Police in Calgary say they've found a body believed to be that of a 5-year-old girl reported missing this week after her mother was found dead, and a suspect has been charged with murder in both deaths.

The Calgary Police Service says the body believed to be Taliyah Leigh Marsman was found by searchers Thursday near a roadway near suburban Chestermere, Alberta.

The discovery comes just days after the girl's 34-year-old mother, Sara Baillie, was found dead in their Calgary home.

Authorities say 46-year-old Edward Delten Downey faces first-degree murder charges. They believe he was known to the mother, the child, and her estranged father.

Police aren't saying how the mother died. An autopsy was planned Friday on the girl.

Calgary Mayor Naheed Nenshi says, "Our hearts are all broken."
