Cause of death unascertained
Dr Lyall says he was not able to determine how Libby Squire died.
He concluded her cause of death remains unascertained.
The pathologist has looked at other mechanisms that could explain her death.
He said: “I have to have an idea of what is relevant and I could explore the different possibilities as I saw them and how they detailed the autopsy findings.”
Dr Lyall said these included looking at possibilities that Libby had drowned, had hypothermia or had been subjected to a violent assault.
He said: “A subtle asphyxial death remains a possibility, this could be some kind of smothering or neck pressure or a combination of both.”
But he added: “While drowning remains possible I am not prepared to say it is the likely explanation for her death.”
He added the level of decomposition to the body made the post-mortem examination harder and said: “There could have been injuries - we just can’t see them.”
Dr Lyall still determined the cause of death was unascertained.
