Tributes poured in for Christophe de Margerie after the chief executive of France's Total oil company was killed when his private jet crashed into a snowplow in Moscow. Three other people were killed, and the plow's operator was drunk, investigators said.

The plow operator was not hurt in the crash, which happened late Monday as the plane was taking off from Moscow's Vnukovo airport, authorities said.

"At the current time, it has been established that the driver of the snowplow was in a state of alcoholic intoxication," said Tatyana Morozova, an official with the Investigative Committee, Russia's main investigative agency. She said investigators are questioning the snowplow driver and other witnesses, The Associated Press reported.

French Prime Minister Manuel Valls called the 63-year-old de Margerie a "great captain of industry and a patriot." French president Francois Hollande expressed his sadness at the news. Russian President Vladimir Putin also sent condolences.

Total's board is meeting Tuesday to discuss how to proceed without de Margerie at the helm. Total share prices were higher Tuesday in afternoon trading in Paris.
