Michael Carlton Paiva, whose late father, Arthur Paiva, was the ringleader in the 1979 killing of Hope College student Janet Chandler, was sentenced to prison for his role in a “dark web” drug conspiracy.

Paiva, 30 was sentenced Thursday, March 9, by U.S. District Judge Robert Jonker.

Paiva suffered years of “heartbreak” after his father was convicted of “unimaginable crimes,” his family said.

He was identified as a buyer of amphetamines and psychedelic compounds – including MDMA, LSD, mescaline and liquid mushrooms – after an international police operation brought down “Silk Road 2.0,” known as a “dark web marketplace” for drug distribution.

He ordered drugs from at least 2013 to 2016, using Bitcoin, a digital currency not sponsored or regulated by the government, or traded through banks or a central clearinghouse. He converted cash into Bitcoin to make online drug buys, the government said.

“Drug traffickers who believe that the dark web and cryptocurrency will provide anonymity and shield them from the rule of law are solely mistaken,” Acting U.S. Attorney Andrew Birge said.

Steve Francis, acting special agent in charge of Homeland Security Investigations, said that “criminals have the false impression that their black market activity using digital currency like Bitcoin are avoiding scrutiny.”
