Olga Moskalyova, 19, gave an horrific hour-long running commentary on her own death in three separate calls as the wild animals mauled her.
She screamed: ‘Mum, the bear is eating me! Mum, it’s such agony. Mum, help!’
Her mother Tatiana said that at first she thought she was joking.
'But then I heard the real horror and pain in Olga’s voice, and the sounds of a bear growling and chewing,' she added. 'I could have died then and there from shock.'
Unknown to Tatiana, the bear had already killed her husband Igor Tsyganenkov - Olga’s stepfather - by overpowering him, breaking his neck and smashing his skull.
Olga, a trainee psychologist, saw the attack on her stepfather in tall grass and reeds by a river in Russia and fled for 70 yards before the mother bear grabbed her leg.
As the creature toyed with her, she managed to call Tatiana several times during the prolonged attack.Tatiana rang her husband - not knowing he was already dead - but got no answer.
In a second call, a weak Olga gasped: ‘Mum, the bears are back. She came back and brought her three babies. They’re… eating me.’
Finally, in her last call - almost an hour after the first - Olga sensed she was on the verge of death.
With the bears having apparently left her to die, she said: ‘Mum, it’s not hurting any more. I don’t feel the pain. Forgive me for everything, I love you so much.’
The call cut off and that was the last Tatiana heard from her daughter.
Half an hour later, Igor’s brother Andrei arrived with police to find the mother bear still devouring his body. Badly mauled Olga was also dead.
