In an effort to solve the long-standing murder case of Sonja Hurler, who was killed in 1981 in Kempten, Bavaria, police are reaching out to individuals who attended a barbecue party organized by the local community of Transylvanian Saxons during the same weekend. The appeal comes after increased public interest due to a segment aired on the ZDF show 'Aktenzeichen XY... ungelöst', which features unsolved criminal cases. The police are particularly keen on hearing from anyone who may have witnessed anything unusual during that time, as even those who were children then might hold valuable information.

Sonja Hurler, a 13-year-old girl, was tragically murdered shortly after she had attended a local celebration, and details surrounding her death have remained murky for decades. The police's outreach effort aims to jog the memories of attendees from that barbecue, which took place near the Kollerbach stream close to Hohenrad, a district of Kempten. Officials believe that eyewitness accounts, no matter how small, could potentially provide new leads in the investigation.

As this case continues to garner attention, local media emphasizes the importance of community involvement and vigilance. The Kempten police are hopeful that by revisiting this old case and resurfacing memories, they will be able to uncover new evidence that could finally bring justice for Sonja and closure to her family. The ongoing investigation serves as a reminder of the unresolved challenges law enforcement faces in cold cases, and the significant role of public cooperation in achieving resolution.
