At David Bain's second trial in 2009, his aunt, Jan Clark, went into some detail of conversations she had with him when he stayed at their home immediately following the murders.
Well worth listening to for anyone who hasn't already trawled through the podcast.
Podcast 4. "The b@stard killed his family" from 00.06.00On the Tuesday evening David read an article about the murders in the local newspaper and appeared distressed, his uncle took him up to the Clark's bedroom for some privacy. A short while later Jan Clark followed him up and found him sitting on the bed with his head in his hands. She recalls saying to him that that was why they didn't want him to read the paper to which David Bain replied, "They lied to me...they weren't asleep...they knew they were going to die...he had to look them in the eye and shoot them".
Interestingly, the newspaper article did not contain any details as to how his three siblings died.
