Ramiro Navarro Quesada, 41, who was arrested in Madrid, early this year and subsequently extradited to the US in late August, pleaded guilty to two counts before Senior US District Judge Donetta W Ambrose in Pittsburgh.
Indian-American US Attorney Shardul S Desai is prosecuting this case on behalf of the government.
The sentencing is scheduled for March 19, 2018. He faces a total sentence of 40 years in prison, a fine of USD 750,000, or both.
"This case is a prime example of how the US will use all available tools at our disposal to identify and apprehend drug traffickers," said Wayne Salzgaber, Interpol Washington Acting Director.
