An hour before he stabbed Sophie Elliott to death, Clayton Weatherston accessed her photo albums on Facebook for several minutes, the High Court in Christchurch has heard.
Kerry Baker, a member of the police electronic crime laboratory in Dunedin is giving evidence on the 11th day of Weatherston's trial for the murder of Miss Elliott.
She was stabbed or cut 216 times at her Ravensbourne home on January 9 last year.
Weatherston (33) admits killing her but denies the charge of murder.
Mr Baker has told the court he examined the computer from Weatherston's office in the Economics Department at the University of Otago and found Sophie Elliott's Facebook site had been accessed and her photo albums looked at until 11.39am on January 9.
Miss Elliott was killed less than an hour later.
Questioned by defence counsel Judith Ablett-Kerr QC, Mr Baker agreed his analysis of Sophie Elliott's Facebook logs, indicated a pattern of access to Weatherston's site followed immediately by access to the site of Sophie's former boyfriend. That pattern was apparent from late December 2007 until January 7.
But Mr Baker said there appeared to be ''something unusual going on here'', and that the visiting of Weatherston's page followed by the other man's might not be a conscious action on Sophie's part.
It could be something to do with the way her Facebook page operated, maybe some sort of linkage between the two, Mr Baker said.
The fact there was definitely a common pattern made him think it was ''some sort of automated thing going on in the background'' and not necessarily Sophie clicking.
''You're speculating about that,'' Mrs Ablett-Kerr suggested.
Mr Baker agreed but said it was ''also speculation to say she's deliberately going from one (site) to the other''.
Evidence from one of the ambulance officers called to the Elliott house at 12.35pm on the day of Sophie's death was read to the court.
Patrick Bain, an advanced St Johns paramedic, said he checked Miss Elliott's carotid artery for a pulse but found none. He then put four defibrillator leads on areas of skin already exposed. He did not disturb any clothing, Mr Bain said.
The Crown closed its case at about 11.30am
