David Bain trial: Week in summary

Monday

The court hears more evidence on bloody sockprints in the Bain house which the defence says must have been left by the killer and a senior policeman in the case says are likely to have been those of the killer.

Forensic scientist Kevan Walsh gives the results of his testing with feet the size of David and Robin Bain's which show Robin was most likely to have left the bloody prints.

But the trial judge, Justice Graham Panckhurst, raises the issue that these tests did not mimic what probably happened in the house.

The first evidence about the crucial timing of David Bain's paper round on the morning of the murders is also heard.

Tuesday

The court hears dramatic new evidence, given to police 13 years after the killing of the Bain family, that Laniet Bain, 18, was scared of her brother David.

Witnesses who say they spoke with Laniet on the day before her death also mention a family meeting called by David for the night before the murders.

One witness says Laniet told her she did not want to go to the meeting, but David would drag her there "kicking and screaming" if she didn't go.

Robin Bain is described as a pacifist who got upset when he saw a bumblebee swatted with a newspaper.

Wednesday

A witness describes Laniet as having an obsessive relationship with David, and being afraid of upsetting him.

The friend of Laniet says she referred to her brother as "my David", and the pair had the appearance of being boyfriend and girlfriend rather than siblings.

Another witness says Laniet revealed to her that she had worked as a prostitute, but hated it and was giving it up.

Optometrist Gordon Sanderson tells how he linked a crucial pair of glasses to David, then changed to the opinion that the glasses belonged to David's mother, Margaret.

Mr Sanderson says he was shocked his change in opinion was not conveyed to the jury in David Bain's first trial in 1995, and other evidence about a lens was also not raised.

Thursday

A fingerprint expert says David's fingerprints were on the rifle used in the killings and were of "recent origin".

Police fingerprint officer Kim Jones says these prints could not have been left by picking up the gun to look at it, but showed considerable force was applied.

He also says a fingerprint belonging to David's brother, Stephen, 14, was on the rifle's silencer, and David left a palm print in blood on the washing machine in which bloodied clothing was washed.
