A 224-pound Russian woman is facing heavy-duty justice for sitting on her husband and strangling him to death with her massive buttocks during a boozy dispute, a report said.

Tatyana O. allegedly refused to let Aidar go even as he “begged forgiveness,” East2West News reported.

Aidar’s daughter saw him pinned face down on the bed and ran to seek help from neighbors in the Russian city Novokuznetsk, according to the news outlet, which cited evidence in the case.

A female neighbor who arrived reportedly decided the couple were in the midst of a domestic dispute and left.

Tatyana said she merely wanted to calm her hubby down after the couple had been drinking.

Aidar died from “asphyxia from blocking the respiratory system” as his face was wedged into the mattress, as Tatyana sat on his neck “using her legs so he could not lift it,” a medical examination found.

The wife “strangled husband to death with her buttocks after drinking too much alcohol,” according to a local media report cited by East2West.

During a trial, Tatyana was convicted of causing death by negligence after a murder charge was dropped.

But the Investigative Committee has announced it is calling for a new murder charge against Tatyana, who had been angry “after drinking heavily.”

After Aidan stopped showing signs of life, “the accused, frightened, shook him and shouted at him to wake him up.”

Question: How is this possible??
