The first of two main defendants in the city's largest gun trafficking investigation pleaded not guilty Friday.
Earl Campbell was arraigned and is being held without bail.
He's charged with personally transporting and selling 90 guns, including two assault weapons.
Campbell and another man allegedly ran separate operations bringing guns up from the Carolinas, sometimes on public buses.
In total, 254 guns were seized and 19 people were arrested during the year-long investigation.
