troy, give us, give us, give us a sense -- sorry about audio interference here. we'll try to get that cleared up. give us a sense what is at stake as this teenager testifies against presumably his parent. >> well, he is going to be testifying against his parent and against his half-sister. as wendy can tell you, as a to recaller prosecutor, the burden is very low for the prosecutors to establish the requisite probable cause. all they have to show the prosecutors, that is, all they show at this hearing a crime occurred and the defendant is likely guilty. so having actual victim of the beating coming in and testifying, means that this woman's going to be held to answer. but she may have a very good defense, that of duress. jon: sara ferguson is her name. she is the 33-year-old half-sister. duress, wendy?
