All of the body parts from the 150 victims, who died in the Germanwings flight in the French Alps, have been now been identified, French prosecutors have said.
But it will take a long time for investigators to match the remains with DNA taken from families of the victims, the Associated Press reported.
More than 2,800 body parts have been found at the crash site, said Marseille prosecutor Brice Robin.
He also said the second black box recorder was discovered buried in the ravine, describing it as "completely blackened" but still "possibly usable". Forty damaged mobiles were also found.
The grim findings come as prosecutors said co-pilot Andreas Lubitz searched online for suicide methods and cockpit door security just days before the fated crash.
Investigators said the 26-year-old, who had previously been in therapy for suicidal tendencies, locked his captain out of the cockpit to deliberately crash the plane.
At a press conference at the crash site, Lufthansa CEO Carsten Spohr said: "We are just very, very sorry that such a terrible accident could have happened in Lufthansa where we put so much focus on safety. We are sorry for the losses that occurred and there are just no words to express this."
But one reporter was ignored by Spohr when he asked about why it took the company so long to publish information about Lubitz's depression episode in 2009. He said: "Sir, your employee crashed a plane. Why are you refusing to take questions?"
