On Friday, Dutch prosecutors called for a sentence of up to 25 years in prison for a Muslim father and his two sons, accusing them of drowning an 18-year-old female family member. The incident allegedly occurred because they believed her “Western” lifestyle was dishonoring their family.

Syria-born Ryan Al Najjar’s body was discovered in a lake near Joure, in the northern region of the Netherlands, on May 28, 2024. Her hands and feet were bound, and her body was found six days after her disappearance. Authorities arrested her father and two brothers, then aged 22 and 24, charging them with her murder, which prosecutors believe occurred on May 22.

“They considered Ryan as a burden to be eliminated,” the Public Prosecution Service stated on Friday. “Simply because she was a young woman who wanted to make her own life choices.”

According to authorities, the male relatives, described as coming from a “strict” Islamic background, allegedly decided to kill her due to perceptions that she was adopting a lifestyle too Western for their family’s beliefs. Reports suggest that Al Najjar faced criticism for her refusal to wear a headscarf in public.

“The immediate cause of her death appears to be a live video on TikTok, showing Ryan without a headscarf and wearing makeup,” prosecutors said Friday. “The video seriously embarrasses the family, according to their posts, as it does not fit within their traditional views.”

“Once the suspects were aware of the video, they started looking for Ryan,” the authorities added. “According to the Public Prosecution Service, her brothers visited her in Rotterdam and convinced her to come along to a remote location the night before her murder. She was taken to Knardijk, where their father joined. There she was killed.”

Local media NL Times identified the brothers as Mohamed Al Najjar and Muhanad, and their 53-year-old father as Khaled. All three were charged with murdering the young woman, while their father was accused of orchestrating the killing before likely fleeing to Syria, prosecutors said.

Investigators say Al Najjar was taken to a remote park where “no one for miles around could have heard her” cries for help. Evidence showed signs of strangulation and drowning, and approximately 60 feet of tape had been used to bind her before she was thrown into the water alive. Prosecutors reported that Khaled’s DNA was also found under his daughter’s fingernails, suggesting he was present during the killing.

“[Khaled] fled to Syria immediately after the murder and left his sons to take the blame. Cowardly,” the Public Prosecution Service wrote in a statement Friday, according to NL Times. “Khaled has completely destroyed his family.”

Dutch authorities added that extraditing Khaled may be difficult because he married a woman in Syria since Al Najjar’s death, the outlet reported. 

The Public Prosecution Service has recommended a 25-year prison sentence for the father and 20 years for each of the two brothers.

The court is scheduled to issue its ruling on Jan. 5.
