Twenty-nine-year-old Mario Jackson pleaded guilty to unlawful transport of a firearm last Tuesday in U.S. District Court in Springfield.
Jackson was arrested in November for aggravated discharge of a firearm and unlawful possession of a weapon by a felon.
Police received a report of a disturbance in the 400 block of South East, heard several gunshots to the immediate northwest, and reportedly located Jackson running into a house with a gun in the 200 block of East Beecher.
Jackson allegedly came out of the house without a gun and was arrested, and officers picked up a gun in that house.
Indictments that have been unsealed reference the November incident; details of the guilty plea remain unsealed on the online federal court system database.
Jackson has a lengthy criminal record that includes three plea deals in the last decade for possession of a weapon by a felon charges that have resulted in prison time. He’s also served a sentence for aggravated battery.
Sentencing is set for October 5th in Springfield. Jackson is in custody of the U.S. Marshals.
