"The criminal suspicions against both the captain and the pilot remain. I assess that another fourteen days will be enough to complete the police investigation so that I can decide on the indictment then," says senior prosecutor James von Reis in a press release.
A new deadline for the indictment is requested for August 28.
Four people, a man and a woman and two young children, were on board. The man and one child were rescued by private individuals, but the mother and one child died.
An analysis of the route of the vehicles involved has been carried out, including based on GPS data.
In addition, data from the cargo ship's "black box" has been obtained, as well as audio and film files with radar images and chart notes analysed, according to the prosecutor.
There is also a technical examination of the sunken pleasure boat as well as forensic medical reports on the causes of death and the injuries sustained by the survivors.
Interviews have also been held, including with the suspects. It is clear that no alcohol or drugs were involved in anyone in the accident.
The prosecutor believes that the actual circumstances surrounding the accident have now been clarified.
"The question of who caused the accident and can thus bear criminal liability is decided by applying the rules of the sea and other standards for shipping, based on the established facts," says James von Reis.
