A 36-year-old Detroit man faces multiple felony charges after authorities uncovered an alleged scheme to smuggle narcotics to inmates across the state disguised as legal correspondence.
John Calhoun was arraigned in Detroit’s 36th District Court before Magistrate Delphia Burton. The charges stem from a multi-agency investigation conducted by the Michigan Department of Corrections, the Michigan State Police, and the Michigan Department of Attorney General.
Prosecutors charged Calhoun as a fourth-offense habitual offender. His charges include one count of conducting a criminal enterprise and one count of delivery or manufacture of 50 to 449 grams of a Schedule 1 narcotic, both of which carry maximum penalties of up to 20 years in prison.
He also faces eight counts of delivery or manufacture of less than 50 grams of a Schedule 1 narcotic, a seven-year felony, and eight counts of bringing contraband into prisons, a five-year felony.
According to investigators, the Michigan Department of Corrections began intercepting suspicious mail sent to prisoners throughout the state in 2024. Authorities allege that Calhoun, who was familiar with prison mail-handling procedures, mailed packages disguised as privileged attorney mail that actually contained illegal narcotics.
The intercepted mail targeted eight separate state facilities: Thumb Correctional Facility, Muskegon Correctional Facility, Earnest C. Brooks Correctional Facility, Bellamy Creek Correctional Facility, Oaks Correctional Facility, Chippewa Correctional Facility, Kinross Correctional Facility, and Baraga Correctional Facility.
State officials highlighted the safety risks posed by prison contraband operations following the arraignment.
“Smuggling narcotics into correctional facilities threatens the safety and security of prison staff and inmates,” Michigan Attorney General Dana Nessel said. “I am proud of the work my office did in partnership with MDOC and MSP to uncover this alleged scheme, and we remain committed to investigating and prosecuting those who attempt to traffic contraband into Michigan prisons.”
Corrections Director Heidi E. Washington emphasized that the department will continue to pursue criminal charges against individuals who attempt to bypass facility security.
“This joint operation reflects the ongoing commitment of Michigan’s public safety agencies to protect the integrity of correctional institutions, uphold the rule of law, and ensure the safety of both staff and incarcerated individuals,” Washington said. “The department continues to invest in contraband technology, improve search procedures, and thoroughly investigate contraband attempts. Any effort to smuggle contraband into a Michigan correctional facility will not be tolerated and the department will seek prosecution every time.”
Col. James F. Grady II, director of the Michigan State Police, also credited the inter-agency collaboration with halting the operation.
“Strong partnerships like this are critical to creating a safe prison environment,” Grady said. “We share a commitment to keeping contraband out of our facilities and protecting the well-being of staff, visitors, and those who are incarcerated. Our detectives did an excellent job.”
The arrests come amid broader efforts by the MDOC to curb the flow of illicit items through its Safe Prisons Initiative, which incorporates body scanners, package scanners, revised legal mail policies, staff training, and expanded intelligence gathering. Correctional officials noted that the department has intercepted more than 100 contraband attempts entering facilities since the start of 2026.
Calhoun is scheduled to return to the 36th District Court for his next hearing on August 24.
