A Queensland police officer went to the site where Daniel Morcombe's remains were found, two days before the man accused of his abduction and murder was arrested, a court has been told.
The Brisbane Magistrates Court has heard bones found at Beerwah on the Sunshine Coast last year were most likely to have come from Daniel Morcombe.
The 13-year-old boy was last seen waiting for a bus at an overpass at Woombye, on the Sunshine Coast hinterland, in December 2003.
Brett Peter Cowan, 43, is before the court for a committal hearing on five charges, including child stealing and murder.
Today, the court heard from forensic experts including Catherine McGovern and police scientific officer Donna MacGregor.
The court also heard from forensic archaeologist Michael Kelly, who is attached to the major crime squad.
He told the court he went to the Beerwah site on August 11 last year, two days before Cowan was arrested.
Ms McGovern said her New Zealand lab was supplied with a toothbrush, which she used to obtain reference DNA samples to compare against the bones found at Beerwah.
She said she obtained six out of 26 possible DNA matches and believed the bones were Daniel Morcombe's.
Ms MacGregor was cross examined about photos of the 17 bones found at the site.
The images proved too confronting for Daniel Morcombe's mother, Denise, who left the court room.
She rejoined her husband Bruce when the hearing resumed later in the afternoon.
The court is also expected to hear from police scientific officers Ashley Huth and Melissa Bell, as well as bone expert Dr Walter Wood.
On Monday, the court heard from Inspector Arthur Van Panhius, who was charged with overseeing the search at Beerwah.
Witness Marie-Ann Cummins testified via video link from Noumea about what she saw at Woombye on the day Daniel Morcombe disappeared.
She told the court she saw an old blue station wagon near a young boy and someone was sitting in the car but she could not see the person.
Ms Cummins said she saw a neatly dressed man standing nearby and he was smiling as if trying to entice the boy into the vehicle, which made her feel uneasy.
Forensic podiatrist Dr Paul Bennett was also cross-examined yesterday about the shoes found at Beerwah last year.
The hearing continues.
