In court, prosecutors played part of Matthew's video confession again, where Matthew is seen talking to his mother on the phone, admitting to her that he touched the children.
Mrs. Durham testified she told Matthew to do whatever orphanage officials wanted him to do.
Defense attorneys say the orphanage director took Matthew's passport and kept him isolated before he confessed on video to molesting the children.
Mrs. Durham said she called her uncle to help find a flight home for Matthew as soon as possible.
The defense also called two medical experts to the stand. A forensic interviewer who is paid $2,000 a day for her testimony, told the court she felt the alleged victims were coached. Another defense expert, a nurse, criticized the way the rape exams were done on the children.
Matthew Durham and his father will take the stand before the case goes to the jury Wednesday.
If convicted, Durham faces life in prison.
