Edis Kayalar, 26, obtained a photo of Crawford's 7-year-old daughter gagged and bound to a chair, a photo her nanny took as a joke during a game of "cops and robbers."
Kayalar, a former friend of the nanny, told Crawford and her husband Rande Gerber in the summer of 2009 that tabloids would pay a lot for the photo.
in September, he was arrested and deported to Germany for being in the United States illegally.
In November, he again called Crawford and demanded $100,000, which led to the charges. Kayalar surrendered to German authorities in November.
German Judge Joachim Spieth said Kayalar admitted asking for money but said it was "to cover costs" for his attempt to warn Crawford that the nanny was not a good influence. "The attempted extortion was at an advanced stage and failed," said Judge Spieth.
