Following its release, Netflix viewers have been praising the series for its ‘truly riveting’ narrative, with some rating it 10/10 on IMDb.
The series, called The Breakthrough, is adapted from a book by journalist Anna Bodin and genealogist Peter Sjölund.
In 2004, Linköping was shaken when 8-year-old Mohammed Ammouri and 56-year-old Anna-Lena Svensson were discovered stabbed to death on the morning of October 19.
Mohammed was reportedly on his way to school, while Anna-Lena was heading to work when the attack happened. According to The Local Sweden, Anna-Lena was stabbed in the stomach, and despite emergency surgery, she succumbed to her injuries.
Mohammed, found nearby with a throat injury, was pronounced dead upon reaching the hospital.
The perpetrator, who used a butterfly knife, managed to evade capture for 16 years. Witnesses described the suspect, believed to be in his early 20s, as calmly walking away from the scene.
It was later determined that Mohammed was attacked first, followed by Anna-Lena after witnessing the event.
The breakthrough came when a 2019 DNA law allowed police to search genealogy databases. This led to the reopening of the case with genealogists’ assistance.
Extensive testing and interviews pointed investigators to the suspect’s family, ultimately identifying the killer in 2020 when a DNA match confirmed their suspicions, as reported by The Guardian.
Daniel Nyqvist, aged 37 at the time of his arrest, was identified as the murderer, having been 21 during the incident.
Nyqvist confessed on the day of his arrest, claiming the murders were unprovoked and attributing his actions to ‘voices’ that compelled him to kill.
In October of the same year, he was found guilty of the murders and sentenced to indefinite psychiatric care.
As of October 2024, he remains in the Regional Clinic in Vadstena under forensic psychiatric care, according to Nyheter24, and he has reportedly changed his name.
The Breakthrough is now available for streaming on Netflix.
