It’s one of these scenarios:

A: SAM or Air-To-Air Missile Strike

B: Bomb Onboard

C: Loss of Control by Pilot’s Due To Pilot Error or Failure of Computerized Fly-By-Wire System Leading to Loss of Control

D: Structural Failure Due To Faulty Maintenance Practices or Previous Damage to Airframe

The “Black Boxes” can provide the answers to the above scenarios. But this is Russia....
