In a DVD interview recorded in March 2016 his niece described being touched on a regular basis when adults in the household went out to play housie at the weekends.
"I didn't know what to do, I didn't know whether to get up. I was starting to feel, I was thinking should I get up, but then I got scared if [someone] would walk up the hall and see. What if they say it's my fault?"
She said she always pretended to be asleep and grew hopeful that by going to bed earlier when others were still awake in the house that he would stay away from her.
"But no. Every time he would come in ... he would just do the same thing. He would come in, pull the covers back and touch me. Then I started feeling yucky and I just didn't know what to do so it just happened."
His touching progressed to contact with his own genitals,and then attempted rape, but stopped after she began living with another family member and the visits stopped, she said.
Yesterday morning Judge Bridget Mackintosh told a jury of eight men and four women not to speculate about the court proceeding being a retrial and to keep an open mind about the case.
In a brief opening address the man's defence lawyer, Bill Calver, also told the jury to keep an open mind and said the defence's case would be that his client was not a child molester and did not interfere with the complainants.
The trial continues today.
