A son and a friend tried to kill his mother out of hatred: the woman was brutally cut with a knife and thrown from a window in St. Petersburg. According to investigators, on November 3, 22-year-old friends arrived at an apartment on Kolpinskoi Road in Pushkin, having previously agreed on retaliation due to personal enmity. One held the 52-year-old woman while the other stabbed her in the head, neck and body. They then threw her out of a second floor window. The mother was saved thanks to the timely help of the doctors. The son and boyfriend have already been charged with attempted murder.
