Mobile phone analysis suggests the man suspected of abducting Madeleine McCann was no more than five minutes away when she vanished, a TV documentary claims.
Other new evidence being aired in the programme includes a former online pal of Christian Brueckner saying the German revealed paedophile fantasies.
It is claimed he said he wanted to “capture something small and use it for days”.
Brueckner, 44 – in jail in Germany for raping a pensioner – wrote from his cell that the idea he abducted Madeleine is as “absurd as starting a nuclear war”.
He lived in the Algarve in Portugal when the British youngster vanished from her holiday villa there in 2007 - when she was three.
Brueckner’s lover at the time, Nicole Fehlinger, 44, says he told her he liked the bodies of pre-pubescent girls.
German prosecutors think he took Madeleine, but he denies involvement and no charges have been brought against him.
Brueckner claims he is happy to "sit back and relax and just wait for their findings."
While protesting his innocence during a letter exchange with an investigative reporter Brueckner admitted being a drug dealer and said he used his battered camper van to traffic drugs.
He wrote: "I was never caught by the police because I followed a few key principles.
"Where possible, only driving during the day so that my battered 'hippy bus' didn't attract attention, only driving on the roads I needed to and, most importantly never provoking the police.
"So that means not committing any crimes, certainly not abducting anyone."
Brueckner added that the idea he abducted Maddie was as "absurd...as starting a nuclear war or slaughtering a chicken."
The documentary will be screened in Germany tomorrow on SAT.1.
