I'm thinking it may have been possibly a late night/early morning crime. Perhaps, since their van was cooling down or repairing itself (not sure about this if they had called for assistance or if it had just overheated*), they decided to sleep there for the night. Less traffic then and not as easy to witness.They were found 12 miles from Liard Hot Springs.
Police received a call at 7:19AM on Monday and went to the scene.
Police have said that there is no serial killer and there is no connection between these murders and any other ongoing investigation. No women have vanished on the highway where they were found.

*Conflicting info on status of van and status of how it was going to be repaired.
