Hearsay may be used in grand jury proceedings. The use of hearsay evidence in grand jury proceedings is a technique used by prosecutors to shield cooperators or witnesses from questioning before proceedings in the district court. The prosecutor can, for example, have an agent testify about who he spoke to and what he learned through an investigation, thus allowing the evidence to be presented to the grand jury without negative consequences.

There are two ways to initiate criminal proceedings in Illinois: (1) charging the defendant by information, which requires a preliminary hearing in the circuit court, or by indictment, which requires presenting evidence to a grand jury. To avoid presenting evidence at a preliminary hearing, the prosecutor instead went to a grand jury to formally charge your son.
Due to the cost of defending a federal criminal case, it is unlikely you will find an attorney willing to take your case pro bono. I recommend speaking to the federal defender program in your area if you cannot afford an attorney.
