Although, local media were reporting the deaths the next day, July 16: Two people found dead south of Liard River Hotsprings - Energeticcity.ca
But things are getting murky, and I can't recall when the big media outlets like CBC or CTV picked up the story.
Fantastic! That means that all tourists in the area had access to the information on July 16 if they were interested in local news. I became aware of the news on July 19, after the identities of the victims were released.
