Susan and Her Husband Lee Are Hardcore Pedophiles

Susan and her husband Lee are hardcore pedophiles. They have six children naturally born to both parents. The purpose for having the children was specifically to cater to their morbid sexual desires as well as feed a lucrative Internet child pornography business. The children range in age from six month to eight years of age. In addition to simply providing nude photographs of the children, the parents sexually assault the children with various objects of their passion. The children are emotionally and physically traumatized. Susan gave birth to all of her children through natural childbirth at home, while under the care of other pedophiles. Therefore, the outside world has remained unaware of the existence of the children. The parents market the abuse through a cover Internet source they believe to be sufficiently protected from the prying eyes of the FBI. Fortunately, one of the alleged pedophiles that recently joined the pedophile chat room thought to be safe was indeed an FBI undercover agent. The agent was able to trace down the location of the couple and secure warrants for their arrest.
What charges will the couple face during their trial? What will happen to the children? What sentencing will the couple possibly face subsequent to their conviction? Would it be possible for Susan to present any form of defense?
