Jacksonville traffic stop leads to fentanyl trafficking arrests, citations

A Jacksonville traffic stop on East Morton Avenue before dawn turned into a fentanyl trafficking case after police called in a K-9 and took two men into custody. The stop happened in the 500 block of East Morton Avenue, a central corridor in the city, and what began as a routine encounter quickly became a narcotics investigation.

Jacksonville Police Department officers stopped the vehicle at about 2:35 a.m. on May 24 and then searched it with the help of a K-9 officer. After that search and the rest of the investigation, police arrested the driver, David E. Grandadam, 47, of the 500 block of South Church Street, on a charge of possession of a controlled substance with intent to deliver. Passenger Matthew J. McCauley, 35, also of the 500 block of South Church, was cited for possession of a controlled substance with intent to deliver and obstruction of justice after allegedly giving officers a false name.

The case carries added weight in Morgan County because local officials have said every overdose death in the county has been fentanyl-related. The county recorded six overdose deaths in 2025, five in 2024, eight in 2023, three in 2022 and five in 2021, a pattern that points to a persistent fentanyl problem rather than isolated incidents.

Statewide numbers show the issue remains severe across Illinois even as deaths have eased from recent highs. The Illinois Department of Public Health reported 3,502 overdose deaths in 2023 and 2,419 in 2024, figures that keep synthetic opioids at the center of public health and law enforcement efforts. The CDC’s overdose prevention resources continue to track fatal overdose data and other indicators for state and local response.

For Jacksonville, the stop on East Morton Avenue shows how quickly fentanyl enforcement can move from patrol work to a broader public safety question. A single traffic stop did not happen on the edge of town or along a remote road. It happened in the middle of the city, where officers say drug activity can move through ordinary streets and where families are left to deal with the consequences of a drug that continues to drive deaths across Morgan County.
