A man accused of murdering five-year-old April Jones has been challenged under cross-examination about what he did with her body.
Mark Bridger, 47, of Ceinws, Powys, denies abducting and murdering April, who went missing near her Machynlleth home on 1 October 2012.
Earlier, he told Mold Crown Court he accidentally knocked her over in his Land Rover but did not remember what he had done with her.
Her body has never been found.
Giving evidence in his defence on Wednesday, he told the court he was drunk and panicked after hitting her.
The prosecution claims he murdered April in a sexually motivated attack after abducting her as she played near her home on the Bryn-Y-Gog estate.
Under cross-examination by Elwen Evans QC for the prosecution, he was asked: "Where is April?
He responded: "I don't know."
Prosecution: "What did you, Mr Bridger, do with April's body?"
Mr Bridger: "I don't know."
Prosecution: "You have absolutely no idea?"
Mr Bridger: "No".
Prosecution: "Is that what you're telling the jury?"
Mr Bridger: "Yes".
Prosecution: "Can you just consider the scale and the scope of the police search... can we agree that whatever you did with April's body you got rid of her so thoroughly that no part of her apart from possibly the blood and bone (remained)... do you agree?"
Mr Bridger went on to say; "I'm not proud of that."
Ms Evans said she wanted to talk about an image on the day "April was abducted by you".
Mr Bridger responded: "I didn't abduct April."
Ms Evans: "Shall we use a more neutral expression... the day she left Bryn-Y-Gog in your car?"
Mr Bridger: "Yes."
She went on to discuss an indecent cartoon image viewed at 12:11 on 1 Oct which involved "duct taping". He said he had not noticed the duct taping.
He had previously been asked why he had silver duct taping on his car's dashboard and said it was used in work.
Asked why he was viewing the image, he said he had "no idea" and it may have been in the wrong file.
He was also asked about the 14-year-old girl who he suspected might be his daughter and why the girl's mother had made a police statement saying she had never had any romantic involvement with him.
He said the mother had been referring to an earlier time when she was 15 but the sexual relationship had taken place years after.
Ms Evans asked: "How easy do you find it to lie through your teeth?"
Mr Bridger: "I don't find it easy, no."
Asked about his fabricated army career, he accepted it was a "fantasy".
Pressed further on why he continued the lie for many years, he asked what was he supposed to do, "change my mind halfway through".
Ms Evans looked at the jury and repeated: "What are you supposed to do, change your mind halfway through."
Earlier the court had heard Mr Bridger's account of how he says he accidentally ran April over as she played near her home.
He said he saw a girl in front of him but as he went to pull away "the car rose up".
He realised what had happened then tried to revive her but "there was no reaction".
He said he had been drinking and panicked so could not remember how he disposed of her body.
The court has previously heard April's blood was found in several locations around Mr Bridger's home.
He also denies intending to pervert the course of justice.
The case continues.
