Silmi received large amounts of cocaine and then sold the narcotic to other drug dealers, the Department of Justice said. He would move the drugs through his business, Global Auto Body & Collision on W. 130th Street.
He would also get large amounts of MDMA (or "molly") and would sell those drugs to other dealers through his auto body shop, court documents said. Between January 2016 and March 2017, Silmi received several kilograms of cocaine and more than 100 kilograms of marijuana, court documents said.
He would then launder money to hide his drug profits, the Department of Justice said.
The investigation into Silmi was led by the FBI.
Silmi was first indicted in December 2017. He was one of 11 people charged with conspiring to sell MDMA, cocaine and marijuana.
"This investigation was the culmination of strong relationships between the various law enforcement partners," Cuyahoga County Sheriff Cliff Pinckney said when the charges were announced. "The Sheriff's Department will always vigorously pursue drug traffickers in conjunction with this partnership."
