In the belief that his then two-year-old son would go on a week-long holiday trip to Turkey with his mother, the father helped to get a passport issued.
But it would be more than six years before the father could see the boy again.
Meanwhile, the boy and his mother have been in Syria, partly in an area controlled by the terrorist group IS and partly in the Kurdish camps al-Hol and al-Roj.
But why they were there, opinions differ.
According to the prosecutor, the woman went to join the terrorist group because she is a sympathizer.
To prove this, he showed during the trial, among other things, screenshots from the woman's Facebook page where it appears that she was in Syria and Islamist propaganda is present.
- She has resided voluntarily in the caliphate, I hope the court agrees with me, said chamber prosecutor Claudio Gittermann in connection with the trial of the woman in Lund District Court.
Women's defense: "Captured"
The woman says that in a life crisis she sought comfort from God and wanted to visit Syria temporarily, but was captured by the terrorist group.
According to her defense lawyer, she has lacked practical opportunities to recover.
- If there are armed guards outside your house who say "you are not allowed to go", then you will get nowhere, said lawyer Lars Kruse in connection with the trial.
But the court does not believe that story.
In the verdict against the woman, one instead follows the prosecutor's line and sentences the woman to three years in prison for gross arbitrariness with children.
The woman is also notified of suspicion in a separate investigation into war crimes that has not yet led to any prosecution.
The woman herself says that she was captured by the terrorist group - hear her here.
