Convicted Felon Headed Back to Prison for Firearm Offense

For Immediate Release
U.S. Attorney's Office, Southern District of Illinois


Tristan Mack, 41, of East St. Louis, Illinois, has been sentenced to 46 months in prison for knowingly possessing a gun after sustaining a felony conviction, Steven D. Weinhoeft, United States Attorney for the Southern District of Illinois, announced today. United States District Judge Nancy J. Rosenstengel handed down the sentence, which includes a three-year term of supervised release. Robinson also agreed to forfeit the firearm he illegally possessed.

Court proceedings revealed that on the evening of December 16, 2017, an Illinois State Police Trooper stopped a car driven by Mack in East St. Louis for speeding and running a stop sign. After noticing an odor of cannabis coming from the vehicle, the trooper conducted a search and discovered a loaded PA-63 semi-automatic firearm in the rear pouch of the driver’s seat, along with 36 grams of cannabis and six ecstasy tablets.

At the time of his arrest, Mack had a prior felony conviction for armed carjacking, an offense for which he was still on federal supervised release after having served 20 years in prison. As a result of his arrest in this case, Mack’s supervised release was revoked and he was sentenced to 21 months imprisonment, a term that will run concurrently with his 46 month sentence.

The case was investigated by the Illinois State Police and prosecuted by Assistant United States Attorney Christopher Hoell.
