Officers Scott Brecht and Jason Omo were on patrol of River Terrace just after 1 a.m. on August 21st to check into complaints of illegal activities there from park neighbors. They came upon two people in the parkâs playground area. Evidence indicated that they were involved in illicit behavior. The pair then began walking in the direction of the officers. The officers checked them out, then discovered an Uzi submachine gun in the place theyâd just left. The weapon was loaded and the selector switch was set to full auto. Both were arrested and charged with weapon offenses and other violations.
