Federal courthouse, Northern District of Iowa in Cedar Rapids

CEDAR RAPIDS – A Grundy Center man who bought drugs on the dark web and sold them in eastern and central Iowa was sentenced July 21, 2020, to more than six years in federal prison.

Jack Arthur Stumberg, age 22, received the prison term after a December 27, 2019 guilty plea to conspiring and possessing with intent to distribute LSD, MDMA, and psilocybin mushrooms.

Evidence at the sentencing showed that, between about 2016 and 2019, Stumberg ordered large quantities of the party drugs over the “dark web.”  The drug packages were delivered to Stumberg through the mail, disguised to look like common household items.  Stumberg then sold the drugs in various communities in Iowa.  He also took the drugs to sell at various music festivals.  The sentencing judge found that Stumberg recruited and directed the activities of an accomplice into the drug conspiracy.

Stumberg was sentenced in Cedar Rapids by United States District Court Judge C.J. Williams.  Stumberg was sentenced to 78 months’ imprisonment.  He must also serve a five-year term of supervised release after the prison term.  There is no parole in the federal system.  Stumberg is being held in the United States Marshal’s custody until he can be transported to a federal prison.


The case was investigated by the United States Postal Service and Grundy County Sheriff’s Office and prosecuted by Assistant United States Attorney Dan Chatham.
