The man accused of murdering five-year-old April Jones told police he had a "mental block" about what happened to her body, a jury heard today.
Mark Bridger, 47, also said he "never thought" of calling 999 after he says he ran her over, Mold Crown Court heard.
The jury were read transcripts of his police interviews for a second day, about events after April was last seen playing near her home in Machynlleth, Wales, on October 1 last year.
Bridger says he accidentally killed the youngster when he ran her over and accepts that he must have got rid of her body but cannot remember how it did it.
He denies abducting and murdering the schoolgirl in a "sexually motivated" attack.
"My intention was to get to the hospital and when I got to the hospital in Machynlleth, I then remembered there was no A&E", he claimed.
He said he then drove to the town's clock tower where he parked, to "think about what to do".
But he added: "I never thought of dialling 999 or 112, I just didn't think."
Instead, he drove "back and forward" around the town.
Bridger said he realised April was dead when he put his hand to her chest and saw that "she was flat on the one side and round on the other".
"That's when I knew there was more to it", he said.
He said he was crying and panicking, and thought: "What have I done? I've now killed a little girl."
When asked about the whereabouts of April's body, Bridger told Det Const Louise Thomas: "I have been over and over and over again in my mind, what I've done and where I've been.
"I just have a mental block of what happened", he added.
At the end of the interview, which took place on October 3, referring to April's parents, he said: "I would like to say to Paul and Coral, I never meant for this to happen, I never meant to put them through this.
"I have got kids of my own, I have known them for years."
Ms Thomas replied: "Maybe you can help by trying to remember."
In a later interview, again on October 3, Bridger said the witness who claimed she saw April climbing into his car is lying and "that is complete fabrication and lies".
He said: "There is no way a girl of that size and petiteness would have been able to get into my vehicle."
"Someone must have told her to say that.. I did not abduct April.. I'd like you to do tests on the car..", he added.
He suggested the police examine his car for April's fingerprints, adding: "If she was awake or alive at that point, she would have held on, she'd have held things".
The jury also heard that Mark Bridger had been taking anti-depressants but "hadn't taken one for possibly a week" at the time he was interviewed by police.
Asked about the indecent images found on his laptop computer, he said he had been researching the adolescent development of one of his daughters.
"As a father who spends every weekend with my daughter, I want to know what's going on."
He also claimed he wanted to protest about the availability of child pornography on the internet.
During the police interview, Bridger was questioned about his background, and said he had spent time in the military.
The officer asked him to tell her about where he served, and he replied: "Some I can tell you about, some I can't."
He listed a number of the countries, including Belize, Mozambique, Namibia, South Africa and Afghanistan.
He said: "Some of it was operational and some of it observational.
"Most of it was mine detection and mine laying."
The jury has previously heard that the Royal Military Police had no record of him ever serving.
The trial was adjourned until 11am on Monday.
