COOK COUNTY CRIMINAL COURTHOUSE — A South Deering man has been charged with illegally buying and selling five guns, including one that was used in an attempted murder in 2015.

Trevon German, 24, was ordered held on $500,000 bail Wednesday on charges of gunrunning, illegally transferring a gun, buying a gun using false information and selling a gun to someone who does not have a valid FOID card.

According to prosecutors, German bought five 9mm guns between May 2014 and February of this year that were later sold to at least three other people.

Two customers were convicted felons who have served time for drug and gun cases, court records show. A third customer, 23-year-old Corey Cowan, used one of German's guns in a 2015 attempted murder, prosecutors said.

In that case, Cowan was arrested and charged in September 2015. He is being held on $400,000 bail, and the case is pending before Cook County Judge Lawrence Edward Flood. Additional details about the case were not available Wednesday.

Authorities said German always intended to sell the guns and provided false information to officials, Assistant State's Attorney Erin Antonietti said during a bond hearing Wednesday.

Judge Laura Sullivan ordered German, of the 9600 block of South Oglesby Avenue, held in lieu of $500,000 bail.
