This serial rapist got away with it by abusing his power. You'll never guess what position he held, and where
Lavrentiy Pavlovich Beria was chief of the Soviet security and secret police (NKVD) under Joseph Stalin during World War II. He was a depraved, power hungry man who ruthlessly used his power for his own entertainment.
On warm nights during the war, Beria's driver would drive him slowly through the streets of Moscow in his armored Packard limousine. He would 'shop' around for young women to his liking, point them out and have them detained. They would then be brought to his mansion where he would dine with them.
After dinner, he would take them into his soundproof office and rape them. His bodyguards were ordered to hand them a bouquet of flowers when they left. If they accepted, it was considered consent. If they refused they would be immediately arrested.
He did not only rape young women, he also murdered some of them and had them buried in his wife's rose garden. The bone remains of several young girls buried in the gardens was found during routine work in 1990.
When he was finally sentenced to death, he begged for mercy and cried so uncontrollably that General Batitsky stuffed a rag into his mouth to shut him up before he fatally shot Beria through the forehead.
