She now refuses to do this or to answer any more questions.
The German organisation that assisted in organising the adoption, Help A Child, refused to make a statement about the case.
In general, Help A Child says they simply went by the documentation they were given by the orphanage and that it is impossible for them to do their own investigation into where a child comes from.
The German Ambassador to Mali, Karl Flittner, says he thinks something went wrong either at the orphanage or at the Malian government department that deals with adoption.
"Our impression is that there was some degree of negligence on the part of the orphanage or of the Direction National de l'Enfance because the investigation into whether this child was really an orphan was apparently not carried out in the proper manner."
Mr Flittner says Germany will be reviewing adoption by Germans in Mali.
"From the German side, the co-operation with this Direction National de l'Enfance will be re-examined and we'll be particularly cautious before they give their agreement now to another adoption from Mali."
Adjaratou is not the only child to have disappeared from Bamako's streets.
Lack of confidence
There is no evidence linking these cases to international adoption, but given the publicity around the Coulibaly case, other families are worried.
Hawa Camera says her five-year-old daughter, Fatoumata Keita, was taken from in front of her house.
Sometimes you have some children who are declared abandoned and the natural parents can be found somewhere in the country”
"I think that my child might not even be in the country any more. Because if you look at what happened to the Coulibaly child, the aim was to take the child away."
Many of the families accuse the police of not taking the cases of missing children seriously. The police deny this and say they investigate fully every case reported to them.
Senior Malian lawyer Lamissa Coulibaly, however, says, he does not have much confidence in the police investigations to try to find a child's family. He says the police lack the means to carry out these investigations thoroughly.
Mr Coulibaly also says there are also serious flaws in the adoption procedures in Mali.
"The children are declared as abandoned, but in fact they are not really abandoned. Sometimes you have some children who are declared abandoned and the natural parents can be found somewhere in the country."
Mr Coulibaly says the parties involved in organising an adoption in Mali are often more keen to get all the papers finalised than to check whether the real parents can actually be found.
The Malian government department that deals with international adoption says that Adjaratou's Coulibaly's case was a one-off and that they are looking into what happened. Mr Coulibaly and others in Bamako will be very interested to hear the results of this review.
For the moment no-one can explain how Adjaratou Coulibaly almost ended up on a plane to Germany.
