A Florida man who authorities suspect had a role in shipping weapons to accused killer and ex-NFL star Aaron Hernandez was indicted Wednesday on charges of witness tampering, obstruction of justice and lying to a federal grand jury that is investigating interstate firearms trafficking.

Oscar Hernandez Jr., 23, was arrested late Wednesday in connection with a federal gun trafficking investigation that stems from the seizure last summer of weapons recovered during searches for evidence in the Odin Lloyd homicide.
