Col. Francis B. Pera of the Army Corps of Engineers said at an afternoon news briefing that additional remains were found during recovery efforts Monday, noting that the team to committed to the "dignified process" of retrieving victims.

Authorities said the death is not related to the American Airlines and Black Hawk helicopter collision that happened on Wednesday night.

The Army Corps said it is first salvaging the jet — which still is believed to have bodies in it — and afterward, it will recover the fallen Black Hawk.
