Counsel assisting the coroner Peter Ah Gee asked Mr Eaton about the extent to which he investigated Concetto "Con" Tati, who had been described as an "intimate partner" of Ms Butterfield.
asserted
who → assist → Butterfield
The inquest heard a statement was taken from Mr Tati, then 38, and that Mr Eaton had written a note saying, "Con has a reputation of belting women".
However, Mr Eaton did not recall whether he looked up Mr Tati's Queensland criminal history or what other follow-up enquiries were made.
asserted
enquiries → hear → history
Mr Eaton said Mr Tati was "certainly a person that needs to be spoken to" but said he did not stand out as a person of "great" interest.

"Specifically with relation to the foul-play hypothesis, did you identify any persons who required elimination as suspects during the course of your investigation?" Mr Ah Gee asked.

"I don't recall identifying anyone, no," Mr Eaton replied.
asserted
Eaton → recall → anyone
Mr Eaton was asked about a Cairns phone number that was the most frequent to appear on a call charge record from the landline at Ms Butterfield's home, and whether he ever enquired as to whom it belonged.
asserted
it → ask → whom
Mr Eaton said he did not recall looking into it and that if any avenue of inquiry was not undertaken, it was because the investigation was not "swaying that way".
asserted
investigation → say → inquiry
"I can't respond or provide an explanation to it, Your Honour, primarily because I don't recall every enquiry or every avenue of enquiry I made in an investigation 28 years ago," he said.
asserted
he → respond → investigation
Mr Eaton said foul play was never definitively excluded.
asserted
play → say → ?
"The three theories were always considered with greater weight placed on the first two," he said.

Items not sent for DNA analysis
Some of Ms Butterfield's personal belongings, including clothing, a resume and identification documents, were found near a lookout along a cane railway at Pin Gin Hill on June 28, 1998.

search → surround → place
Mr Eaton said he would have been "surprised" to find any biological material given the time that had passed.
asserted
that → say → time
Mr Eaton agreed with Mr O'Donoghue's barrister James Sheridan's proposition that the absence of blood or fluids on Ms Butterfield's items would have contributed to a decision not to send them for DNA testing.
asserted
absence → agree → testing
However, he said: "There was a heavy focus on the suicide [theory]."
asserted
he → say → theory
"In my view, discarding those items at such a prominent location would not be the behaviour of someone who has been involved in foul play of a missing person,"he said.
asserted
who → discard → person,"he

asserted
envelope → postmark → handwriting
Mr Ah Gee asked Mr Eaton whether he had considered if someone else could have mailed it.
uncertain
someone → ask → it
"I don't recall having that thought process but it wouldn't make sense to me that someone would have posted it on her behalf," he said.
asserted
he → recall → behalf
The envelope was checked for fingerprints but none were found.

none → check → fingerprints
