A Russian woman has been convicted of fatally stabbing her teen model sister 189 times in a jealous rage and sentenced to 13 years behind bars for the brutal crime, in which she also gouged out the teen’s eyes, according to a report.

Elizaveta Dubrovina, 22, was found guilty of murder “with particular cruelty” by a court in St. Petersburg, where she learned of her fate without showing any emotion as he sat in a glass cage, The Sun reported.

The woman, who was envious of Stefania’s good looks, had blamed the brutal 2016 attack on her sister’s alleged lover, Alexey Fateev, 44, in whose apartment the victim died as he was out shopping.

“Due to personal hostile relations, the defendant stabbed her sister at least 189 times with a knife into her vital organs, and cut off her right ear,” the city prosecutor’s office said in a statement. “The victim died at the scene from multiple wounds and blood loss.”

Dubrovina was cleared to face trial recently after undergoing compulsory psychiatric treatment.

Fateev told investigators he found Stefania’s naked body and managed to stop Elizaveta from fleeing.

The prosecutor added that Elizaveta “scoffed at her sister, causing her to endure excruciating pain because of her dislike,” adding that “she copied the image of her younger sister – the same hair color, the same lipstick.”

“There are photographs of both sisters hugging each other but there is no doubt that the elder sister envied the younger one,” the prosecutor said.

The sisters’ aunt, Ekaterina Dubrovina, has called Stefania’s death a “shocking tragedy.”

St. Petersburg showman Stas Baretsky, 45, who had known the sisters, said the prison sentence was too severe.

“I hope that the sentence to be reconsidered, as I believe she is not guilty,” he said.
