A woman named as an alibi witness for the man accused of killing Daniel Morcombe says she can't recall if he was at her home on the day the schoolboy disappeared.
Sandra Drummond has told Brisbane Magistrates Court her memory about whether she saw Brett Peter Cowan on December 7, 2003 is hazy.
But she said it was possible Cowan's statement to police about his whereabouts on that day was true.
"I used to live on the way home to his place so he'd drop in sometimes, and sometimes there was no reason except he saw us in the yard, so I don't know," she told the court on Monday.
Cowan's lawyer Tim Meehan asked, "So your response is if he says he was there, he was probably there, but you just don't know?"
Ms Drummond replied, "Yes."
She was giving evidence at Cowan's committal hearing.
Cowan, 43, is charged with murder, child stealing, deprivation of liberty, indecent treatment of a child and interfering with a corpse.
Ms Drummond was also questioned about her own movements on the day Daniel, 13, went missing while waiting for a bus on the Sunshine Coast.
She said she couldn't recall if she had attended her grandchild's birthday party on that day or the following weekend, and said she might have gone to the RSL club that afternoon.
The court heard her membership card had been used that day.
Ms Drummond was the only witness to give evidence on Monday in open court.
Six police witnesses will now testify behind closed doors, before the court reopens for the final two police witnesses.
Magistrate Brendan Butler is then expected to decided whether to commit Cowan for trial.
"We don't need any motivation," he said.
"On the way here this morning we drove past the cemetery where Daniel was laid to rest, we drove past the abduction site.
"The blood is flowing on the way here and you know the purpose of today."
