It's also a known psychological phenomenon that people who are grieving often see their deceased loved one's face in a crowd. I experienced this myself repeatedly when my father died and it was very unnerving. I imagine that Sarah, although not exactly grief-stricken, is experiencing something similar due to stress and trauma.
As I've explained before, misidentification is highly unlikely with today's science. Even if there hasn't yet been a definitive DNA identification, the pathologist will have been able to say whether or not the body is the same height, body shape, hair colour, age etc as Callum. Denton looked nothing like him.
