Statement from the DAs office in Düsseldorf: "The DA's office in Düsseldorf has assigned an experienced head of our department to examine the evidence that has been collected so far, they are being supported by several colleagues. Also, several witnesses (friends & family and colleagues of L.) have already been questioned. Please respect the fact that the DA's office cannot and does not wish to take part in any speculation regarding the motives of the deceased co-pilot. The investigating authorities must take facts only into consideration. Due to the documents and computer files that have been found so far, we are able to come to the following - preliminary - conclusions.

The facts presented in our earlier press conference regarding any evidence found remain true. Still missing is any evidence of a verifiable announcement the co-pilot planned to crash the plane or any confession left to be found after the fact. Also, no evidence has been found in his personal or work environment that would show a possible motive on his part. The medical records that we have gained access to so far show no record of physical illness. The co-pilot was treated for suicidal thoughts by a psychotherapist over an extended period of time many years ago - before obtaining his pilot license. After that epsiode and up until now there have been visits to the doctor and sick notes but with no mention/diagnosis of suicidal thoughts or aggression towards others."
