You're reading: Remains of all 45 Russian plane crash victims ID’d

JAKARTA, Indonesia — Forensic experts say they have identified the remains of all 45 people on board the Russian plane that slammed into a jungle-clad cliff atop an Indonesian volcano.

It’s not clear what caused the Sukhoi Superjet 100 to crash during a May 9 demonstration flight for potential buyers.

Authorities are still analyzing the cockpit voice recorder found at the bottom of a steep ravine. But they have given up hope of recovering the flight data recorder, which keeps track of all instructions sent to electronic systems on the aircraft.

Col. Anton Castilani, a forensic expert with the police, said on May 21 all victims have been identified. They include 35 Indonesians, eight Russians, one Frenchman and an American.

The remains will be handed over to relatives or country representatives.
