The girlfriend of Daniel Morcombe’s accused killer says he took her to an isolated clearing where the Crown alleges the teen was killed.

The ex-girlfriend of the man accused of killing schoolboy Daniel Morcombe said he took her to the isolated spot where he allegedly murdered the teen.

Leticha Harvey told court Brett Peter Cowan took her via a back road to a small macadamia farm where there were some sheds and uninhabited demountable houses.

“It seemed very away from everywhere, secluded,” Ms Harvey told Cowan’s trial in Queensland’s Supreme Court.

She said she formed a relationship with Cowan in 2008 when she was 18 and had a child with him in 2009.

The Crown is arguing Cowan confessed to choking Daniel after the 13-year-old fought against his sexual advances in a demountable house on a macadamia farm.

Cowan, 44, has pleaded not guilty to indecently dealing with Daniel, murdering him and interfering with his corpse in 2003.

In his opening statement, prosecutor Michael Byrne QC said the Crown would argue Ms Harvey’s evidence demonstrated Cowan knew of the spot.

She said they stayed one to two hours looking through the buildings.

“He was with me and occasionally he would walk away and do I don’t know what,” she said.

She returned with police in August 2011 and noticed the demountables were no longer there.

The trial has previously heard there was one demountable house at the macadamia farm in 2003 which was removed in either 2005 or 2006.

Cowan’s former wife told the trial that on the afternoon of December 7, 2003 – when Daniel disappeared – her then husband went out to borrow a mulcher about 1pm.

He returned about 2.40 or 3pm, Tracey Moncrieff, 39, said.

The court has heard Daniel vanished from under the Kiel Mountain Road overpass sometime after 2pm.

Cowan told police two weeks after Daniel’s disappearance he drove under the overpass on his way to pick up the mulcher but didn’t see anyone there.

Ms Moncrieff said she met Cowan at her local church and married him in 1999.

They had two children before separating in 2004.

She agreed with prosecutor Glen Cash that Cowan had a habit of standing a certain way.

She said he would often stand on one leg with the other foot resting on his knee or against a wall.

“If he’s leaning on something he always seems to have one leg up,” she said.

Several witnesses say they saw a man under the Kiel Mountain Road overpass leaning against an embankment with one foot raised and resting against the wall.

The man was seen near a child matching Daniel’s description shortly before the schoolboy vanished.

The trial continues.
