Ottawa police searching for missing 28-year-old woman

Searchers looking for a six-year-old boy who went missing in mountainous terrain in Alberta a week ago say the likelihood he’s still alive is less than five per cent, but they say the search has not been scaled back.However, Adam Kennedy with Alberta Search and Rescue says tactics will change given the low probability Darius Macdougall is still alive, such as focusing less on using heat-seeking aerial cameras.
