SEEING images of Daniel's remains on a large screen in a courtroom could not have been easy for the Morcombe family.

The tiny bone fragments and pieces of clothing are all they have left of the 13-year-old after he went missing almost nine years ago.

And they have been fighting to get him back for 15 months since those pieces were found during a search of bushland at Glasshouse Mountains.

"Clearly some of those photos capture images that are disturbing to family members and make it difficult for us to cope with," Bruce Morcombe said.

The Morcombes could be seen stealing glances at the man accused of doing despicable things to their son.

Mr Morcombe said he hoped the rigorous testing of DNA evidence during this two-week portion of accused man Brett Peter Cowan's committal hearing would allow authorities to finally return Daniel and let the family lay him to rest.

Cowan sat calmly in a dark suit jacket with green shirt and tie during the hearing.
