Overview
- Police in Mönchengladbach and the Krefeld public prosecutor arrested a 59-year-old former store detective last week and placed him in pretrial detention on suspicion of the January 1995 murder of Lidl branch manager Sonja K.
- Investigators say new forensic methods allowed DNA to be extracted from tiny skin flakes preserved on foil from the original evidence and that a match came after voluntary saliva samples were collected from former store detectives in early 2026.
- Prosecutors told a court to issue an arrest warrant listing the murder characteristic as Habgier, or greed, while saying a motive to cover up other acts has not been ruled out.
- Police continue to search for additional perpetrators and for the victim’s missing key ring, which included the safe key used in the robbery that accompanied the killing.
- The arrest offers long‑awaited news for the victim’s family and keeps open broader questions about the case, including how the attackers entered the store and whether the evidence now on hand will lead to further charges.
