THE Emma Caldwell murder suspect continued to contact sex workers and saunas in the week after the alleged killing.

Jurors heard this included almost 30 calls and messages in one day.

Iain Packer, 51, is on trial and denies a total of 46 charges involving multiple women including the murder of 27-year-old Miss Caldwell at Limefield Woods in Biggar, South Lanarkshire on April 5, 2005.

The High Court in Glasgow heard there was no contact between numbers used by the pair.

But, one of the last people to get in touch with Miss Caldwell was said to be one of the men who Packer has incriminated as instead being involved in the alleged murder.

Police Scotland crime intelligence analyst Evita O'Malley gave evidence at the trial on Thursday.

She compiled reports having been asked to examine phone numbers used by both Packer and Miss Caldwell before her death.

The trial has earlier heard how he had previously paid for sex with Miss Caldwell.

Prosecutor Richard Goddard KC put to Miss O'Malley that there appeared to be "no contact" between three numbers used by Miss Caldwell in 2004 and 2005 and any by Packer.

She replied: "That is right."

The court heard on April 7, 2005 - two days after the alleged murder - that Packer made 27 calls and texts to Glasgow saunas or sex workers.

This was further contact on April 10, 14 and 21 including to an escort agency.

There had also earlier been 60 calls in a 10-hour period on March 10, 2005.

The court was also told about a string of cash withdrawals Packer made on these days.

Jurors heard the last outgoing call on the number used by Miss Caldwell was around 9pm on April 2.

She was, however, contacted four times prior to her death.

This included a one-minute and 16-second phone call from a man who is one of four Packer has lodged a special defence of incrimination against.

The final incoming contact on Miss Caldwell's number was a text from another man at 1.27am on April 5.

Miss O'Malley also spoke about phone "cell sites" triggered when a device is in the area of one.

Miss Caldwell was said to be in the region of one in Norfolk Court in city's Gorbals at the time of the last text.

The witness told the court this "cell site" could cover the Glasgow Green area of Glasgow.

Mr Goddard asked Miss O'Malley: "Are you aware a witness sighted Emma Caldwell in the London Road area between midnight and 1am (on April 5)?"

She replied: "Yes, I am aware."

The advocate depute: "That area would be served by Norfolk Court?"

Miss O'Malley: "Potentially."

The court heard the most common "cell sites" triggered by Packer's number was near his home and another "around the Glasgow Green area".

But, jurors were also told there was nothing to link any of the numbers used by himself of Miss Caldwell to the area of Limefield Woods.

In a bid to catch Miss Caldwell’s killer, the court later heard there was a “lengthy and painstaking” review to try and recover any DNA from items originally examined around the time of the death.

Amanda Pirie was one of the forensic scientists involved in this.

But, despite advancements in techniques used, Miss Pirie agreed with prosecutor Mr Goddard the review “did not help address” who may have been involved in the death.

Items checked included a cable found around Miss Caldwell’s neck when her naked body was discovered in a ditch in the woods.

There was also a hair clasp and ring she had on as well as drinks cans and condoms amongst litter collected at Limefield.

A blue van used by Packer was also examined, but there was “no trace” of any female DNA found.

The report stated: “In our opinion, the scientific findings do not help address with whom Emma Caldwell had recent physical contact prior to and/or around the time of her death

“The results from our examinations do not help address who may have been involved in Emma Caldwell’s death.”

The court heard one reason that may have had an effect was Miss Caldwell’s having no clothes or footwear on when she was found.

The report further added: “In our opinion the lack of significant findings…are more likely to be as a result of the above actions and measures taken by the assailant.”

The trial, before Judge Lord Beckett, continues.
