A 26-year-old Armenian woman, a mother of three, was stabbed to death in Russia's Tyumen by a pizza delivery man.

Nune Sargsyan was found with 40 stab wounds in her apartment on April 21, police reported. The woman was celebrating her birthday and was waiting for pizza delivery.

Zakhar Kovrigin, 22, delivered pizza and decided to enter the apartment again to grab gold and money. He knocked at the door once again asking to verify the check and demanded money, threatening Nune with a knife. The woman gave him golden rings and money, but being afraid that she would call police, Kovrigin stabbed her to death.
