"Then we have to have different opinions about the reasonableness of it," says the prosecutor, when the defendant again replied that he did not remember.

The defendant had a destructive drug addiction for a couple of years, even during the acute time period that the suspected murder was allegedly committed. He believes that it makes it even harder for him to remember.

There is no forensic evidence linking the accused to the suspected murder of Marua Ajouz. The evidence presented by the prosecutor is a jigsaw puzzle of witness statements, mobile phone placements and a hair found on the sack in the beech forest that could belong to one of the defendants' friends, as well as that corpse dogs made marks on the kitchen floor of the defendant's then apartment.

The defendant's relationship with Marua

When the defense asks the defendant about the relationship with Marua Ajouz, he says that they have been together 2-3 weeks and that it ended in the same time period as Marua's disappearance. But that they were also in the same circle of acquaintances.

"How much time do you meet over a period of two to three weeks?" asks the defendant.

"I don't know, I don't remember, but certainly not very much," the defendant replies.

Denies any wrongdoing

"If you have killed Marua, you should remember this night," the prosecutor said.

"But I haven't, I haven't taken her life," says the defendant.

The prosecutor believes that there is a person who heard the defendant say that he shot Marua Ajouz by mistake.

"That's," says the defendant, who has no memory of whether he had a weapon or not.
