juvenile injustice within the az. systema

please anyone that will listen.I have a son Uriah that has been severly mistreated by the Mohave County ,Az. justice?system.and is suffering still as a result of severe mistreatment by a sheriff deputy who was biased on a crime scene investigation,or should i say lack of one.Uriah was severly traumatized by force with a gun to his head face down and made to watch his companion lay dying 30ft.away with a gunshot to the head, by the same people that held him. The people responsible for this were deemed acting in self-defense, for shooting an unarmed man in the head twice and at close range as he was attempting to leave a public petting zoo. My son,Uriah was arrested at the scene, and the admitted killers were never even investigated it was just to easy for the sheriff to arrest a 14 yr. old boy,who could be manipulated and frightened into taking a plea agreement, than to do an investigation and court process on two adults.Our son,Uriah was totally stripped of any and all rights,and we the parents were also. we were not informed of the arrest, proceedings,were not allowed to talk,visit or have any contact with our son and that still stands as it has for the past 18 mos. Since July 11,2000 when this homicide took place was the last contact with our son and that was when he left with a friend to go driving in the desert 2 miles from our home to a petting zoo, where the owners a man and women shot and killed his friend Jerry for having a verbal altercation.please anyone that can help in anyway, respond asap. i really don`t know how much longer our son,Uriah can hang on in Juvenile prison awaiting some help, we are very much concerned for his life. we have a web site that tells some of the facts please view at: www.geocities.com/bonnieslaw2000/Uriah_s_page.html and contact us at bonnieslaw2000@yahoo.com or 760 326-3766 please this is urgent
