Mazur's blood alcohol content was three times over the legal limit and medical tests showed cannabis in his blood
The son of the head of Russian pipeline company Rosneftegazstroy was sentenced to 6,5 years in prison by a London court Friday for involuntary vehicular manslaughter.
Ivan Mazur Jr, 22, crashed his Mitsubishi Lancer at 129 kilometers per hour into a lamppost on the Piccadilly Underpass on Nov. 6, killing front-seat passenger Charles Green, 21. Green's 22-year-old fiancee was also injured.
Mazur's blood alcohol content was three times over the legal limit and medical tests showed cannabis in his blood, the police said in a statement.
After hitting the lamppost, the car crossed directly into the path of an oncoming BMW sedan. A Mercedes then collided with the BMW. All six occupants of the BMW and the driver of the Mercedes were hospitalized.
Mazur, a Cambridge University student and former Eton schoolboy, was also disqualified from driving for 8 1/2 years by the Southwark Crown Court.
