Acting on behalf of the defence, Toby Hedworth QC questioned whether this would mean the assailant would have had to be “sufficiently mobile” to sit upon her.
He also asked whether the narrowing of one of Pek’s coronary arteries, which was also discovered during the post-mortem examination, could have played a role in her death.
Dr Bolton confirmed it was unlikely to have killed her but may have meant “death came a little more quickly”.
The court later heard from Detective Constable Mark Wedderburn and Detective Constable Joanne Glendenning who were involved in collating evidence for the case.
This included images of an embankment outside The Bosville Hotel on the Isle of Skye, where Alan Fong and Pek had been staying days before she died.
Mr Fong is believed to have tripped over a pipe in the dark and fallen down a drop of around 15m.
He sustained several injuries that saw him being taken to the MacKinnon Memorial Hospital and kept in overnight, and given a mix of painkillers including morphine and codeine.
The court was also played a recording of the 999 call the couple’s son Alonzo made to the emergency services soon after 7am on Dec 6.
Alonzo is heard saying: “Okay, he told me, I think they had some argument of some sort and then I think he lost it.
“And then he told me he covered her just to make her keep quiet … he told me she’s not breathing as well, so can I get medics as well?”
The call handler is also heard saying to a colleague: “‘He thinks his dad has killed his mum at the hotel”.
CCTV footage from the County Aparthotel on Westgate Road, Newcastle shows police officers entering the lobby and hurrying along the corridor.
Body-worn camera footage shows Mr Fong opening the door and stepping into the corridor, as instructed.
Pek’s body is then visible, lying on the bed with her legs hanging over the edge and her face covered by a pillow.
When ambulance workers arrived at 7.30am, they are heard asking Mr Fong: “How long has she been like this for?
He replies: “I don’t know.”
The worker asks: “You don’t know?”, and Mr Fong says: “‘It must be long”.
The case continues.
