Zakhra Rzayeva, 3, was found dead behind a high pile of snow in the playground at a kindergarten in Moscow.
The temperature was believed to be around -5C outside the nursery known as Kindergarten 2120.
Teachers are accused of forgetting about her and leaving her in the sub zero conditions for two hours.
And by the time they remembered it was too late, despite the efforts of paramedics to revive her.
Russian cops are now investigating, and her parents Rizvan Rzayev and Gulnara Shakhadat were too distressed to speak.
Ramil Gadzhiyev, a friend of the family, said: “God forbid that any parents have to go through this.”
He added: “At noon they have lunch. They noticed the child lying on the ground.
“That’s what I heard when I asked them – but I don’t know what really happened.
A major investigation has been launched into the girl’s tragic death involving Russia’s Investigative Committee which deals with serious crimes.
Local media reported: “Kindergarten teachers forgot a three-year-old girl outdoors after a walk.
“They remembered about her only two hours later. “The girl was found behind a snowdrift – she was dead.”
