A jury has reached a verdict in the trial of Daniel Morcombe's accused killer Brett Peter Cowan.

The six men and six women of the jury retired to deliberate their verdict at 12.13pm on Wednesday.

Their deliberations continued for three hours and 15 minutes, before the court was adjourned for the day.

It reconvened at 9.30am on Thursday. Shortly before 1pm, it emerged that the jury had reached a verdict.

Reporters and interested members of the public are seated in the public gallery, with high-profile child protection campaigner Hetty Johnston among them.

Nearly a dozen seats have been reserved for the homicide detectives involved in the eight-year-long investigation into Daniel's disappearance, while 15 seats have been reserved for the Morcombe family.

Television crews have assembled outside the courthouse, with satellite trucks lining the footpaths of George and Roma streets.

The court heard from 116 witnesses over 16 days of the trial. The prosecution and defence delivered their closing statements to the jury over another three days.

The jury retired shortly after Justice Roslyn Atkinson completed her summing up on Wednesday.

Before letting them go, Justice Atkinson gave the panel 13 questions to answer when considering their verdict for each of the three charges against Mr Cowan.

To find him guilty of murder, in sum, jurors must be satisfied beyond reasonable doubt that Daniel Morcombe is dead and that Mr Cowan intended to cause his death, the judge said.

Justice Atkinson has also left it open for the jury to find Mr Cowan guilty of manslaughter.

She thanked three reserve jurors for their time and told them they were no longer needed.

Mr Cowan, also known as Shaddo N-unyah Hunter, is charged with one count each of murder, indecently dealing with a child under the age of 16 and improperly dealing with a corpse.

He has pleaded not guilty to all charges.

Daniel, 13, vanished while waiting for a bus at Woombye on the Sunshine Coast on December 7, 2003.

Mr Cowan was arrested in August 2011 following a lengthy undercover police operation.

Prosecutors say video and audio recordings of the accused confessing to the murder are proof he killed Daniel.

Mr Cowan's defence team says their client fabricated the confession partly because he believed he stood to gain a large sum of money.
