The CNN story is a bit confusing. The 2 people who are still missing are not believed to be in the summit area, rather they are assumed to be down at a lower elevation on the Mount Whitney trail near Whitney Portal where they were on a planned 3 day hike.

Regardless of where the 2 missing are, I hope there is a good outcome for the both of them.
