The two victims of last Sunday’s (July 29) tragic climbing accident in the Heart Creek area have been identified, but police and Alberta Parks are still unsure about what caused the pair to fall almost 100 metres to their deaths.

Calgarians Ranjit Sidhu, 31, and Jane Vuong, 25, were rappelling down the sport climbing route called Sciatica, which is a 5.10d six-pitch route in the Heart Creek area about 15 kilometers east of Canmore.
