Officials said on Saturday that they recovered 42 sets of remains amid the investigation into the Jan. 29 Potomac River midair collision, and plan on releasing more details in coming days.

An American Airlines plane with 64 people on board collided with an Army helicopter over Washington, D.C., and crashed into the Potomac River.

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