Rosneftegazstroi Chief's Son Jailed in London

Ivan Mazur Jr., the son of the head of a state company, was sentenced to 6 1/2 years in prison by a London court Friday for involuntary vehicular manslaughter.

Mazur, 22, crashed his Mitsubishi Lancer at 129 kilometers per hour into a lamppost on the Piccadilly Underpass at around 2.45 a.m. on Nov. 6, killing front-seat passenger Charles Green, 21, London Metropolitan Police said.

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.

Ivan Mazur Sr. is the head of Rosneftegazstroi, a state-owned company that builds pipelines.

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.

The Mitsubishi Lancer Evolution 8 is described by manufacturers as "the fastest production four-door saloon in history," and can accelerate from 0 to 100 kilometers per hour in 3.5 seconds.

Mazur, a Cambridge University student and former Eton schoolboy, was also disqualified from driving for 8 1/2 years by the Southwark Crown Court.
