A Chicago man has been found guilty on federal drug charges after prosecutors proved he turned Greyhound bus routes into a personal meth-supply pipeline between Illinois and Iowa — a scheme investigators say he repeated multiple times before finally getting caught with nearly two pounds of ice methamphetamine in a backpack.
Jonathan Quinn Carter, 37, was convicted on eight counts of distributing methamphetamine following a three-day trial in Cedar Rapids. Jurors deliberated for approximately five hours before reaching their verdict.
Prosecutors described the operation as simple but highly effective: Carter boarded a bus in Chicago carrying pound quantities of ice meth, sold to Iowa customers, then returned to Chicago to restock — repeating the cycle.
Investigators first noticed Carter in November 2024 when Illinois State Police stopped a vehicle he was traveling in near Grundy County and allegedly discovered four pounds of methamphetamine. That traffic stop triggered a federal investigation.
Undercover agents then enlisted a confidential informant in Iowa, who made a series of controlled drug purchases from Carter while law enforcement tracked his movements between Chicago, Cedar Rapids, and Iowa City. On August 19, 2025, officers stopped an Uber that Carter had boarded after arriving in Iowa City on a Greyhound bus from Chicago. When police pulled over the rideshare on a headlight violation, they found approximately two pounds of methamphetamine in Carter’s backpack.
In total, law enforcement officers purchased half-pound quantities of ice methamphetamine from Carter on five separate occasions, and he helped arrange three additional drug transactions. Carter remains detained while awaiting sentencing. He faces a mandatory minimum sentence of 15 years and a maximum of life in prison, along with fines of up to $20 million.
