Authorities recovered all of the 67 victims from the Potomac River less than a week after an American Airlines flight collided with a military helicopter in the Washington, D.C., area.

Search and recovery efforts are over after the crash last Wednesday, with 66 people identified, Washington officials said in a statement Tuesday. The chief medical examiner’s office is still working to identify the final victim.

Officials called it a “significant step” to bring closure after the collision.

“Our hearts are with the victims’ families as they navigate this tragic loss,” the statement said. “We extend our deepest condolences and remain committed to supporting them through this difficult time.”

Authorities will turn to clearing the wreckage from the Potomac River.

The National Transportation Safety Board is investigating the cause of the crash Wednesday night, when American Airlines Flight 5342, traveling from Wichita, Kansas, collided with an Army Black Hawk helicopter outside Reagan National Airport in Arlington, Virginia.
