David insisted that Laniet was home on the Sunday night prior to her murder.

Cross examination from Mr Bates of David's Auntie at trial in 2009

Q. Did you talk about Laniet on this particular morning and was it back to the 20th?

A. Yes. I asked David, I was surprised that Laniet was at home because I knew at that time that she was living out at Robin’s house in Taieri Beach and I said to him that, “Why was Laniet home?” I was surprised that Laniet was at home. And he said that he had in fact gone to the museum café and talked her into coming home.

Conclusion

This seems to show that Laniet did not want to be at home on the Sunday night before her murder but in fact David insisted that she was home as attested by his Auntie.
