Many states (and I think Texas is one) have laws
which establish a procedure by which a citizen can bring evidence to a
grand jury's attention, without going through a prosecutor. To find out
if Texas has such a law, you can check on FindLaw,
www.findlaw.com - look for the
Texas statutes that govern grand jury practice and the Texas rules of
court dealing with grand juries. Or, you can try calling a Texas law
professor who teaches Criminal Procedure and ask him or her about this.
Or, as a final alternative, you can call the clerk of the court where
the grand jury sits and ask the clerk how you would go about getting
evidence directly to the grand jury.
Even if Texas does not have a statute or court rule
establishing a formal procedure for this, you can always contact the
clerk of the court that supervises the grand jury in your county/area
and ask if you can submit evidence to the grand jury. The clerk can tell
you how, and if, you do that.
