It emerged that the police are looking for an unknown car that may have been involved in the murder of Xavier Durlinger. On May 11, the day of Xavier’s disappearance, the vehicle drove on Kapellerweg, near the Kollenberg, at around 00:45 hours where he was found dead. It also appears that the watch that the 19-year-old victim was still wearing, as shown on camera images, is gone. The police also want to know whether the resident of Sittard purposely walked to the Kollenberg or whether he was lured there. He was found dead more than a week after he went missing.
