Thirty-eight-year-old Mumtaz Sattar lost her life in mysterious circumstances shortly after arriving in the Punjab with her husband Abdul on Saturday morning.
Mr Sattar - who is under pressure to stay in Pakistan and answer questions about the death - said the couple had drunk spiked tea before they were thrown out of a taxi they caught from Lahore Airport.
However, a post-mortem report carried out in Pakistan found a bone in Mrs Sattar's neck, the hyoid, was fractured.Professor Anthony Busuttil, of Edinburgh University, was asked to review that post-mortem by Glasgow solicitor Aamer Anwar, who is acting for Mrs Sattar's family.
Mr Busuttil, speaking through Mr Anwar, said: "If the fracture were present at the time of death it would indicate forceful squeezing of the neck i.e throttling which could have caused death. "
The professor and Mr Anwar are now waiting for further toxicology reports from Mrs Sattar, who was buried 14 hours after she died because, her husband said, there was no cold storage available to hold her remains.
It is expected Mr Busuttil will ask further questions before preparing a full report on the death on behalf of the family.
Mr Sattar said he and his wife took a taxi from outside the security perimeter of Lahore Airport for the journey to Faisalabad, another major Punjab city, to visit relatives. He then described how he and Mrs Sattar were given spiked tea during a break on the journey in the town of Shakhot. They were then thrown out of the cab and robbed of their passports and cash. He survived. She did not.
Mr Sattar, who is 45 and originally from the Punjab, remains in Pakistan. Sources said he had applied for emergency travel documents to leave Pakistan but police are understood to wish him to remain to help them with their inquiries. Police Scotland's Major Investigations Team, meanwhile, is investigating reports of "domestic incidents" involving Mrs Sattar in Scotland.
Mr Anwar said: "There are great number of questions that still need to be answered by Mr Sattar if his wife's killers are to be caught.
"Mr Sattar could find himself in serious trouble if he should make an attempt to return to the UK."
