Overview

• Police took the 61-year-old into custody in Mettmann on May 27, 2025, under a court-issued warrant for bodily harm resulting in death.
• Investigators allege the suspect stabbed his 45-year-old roommate with a kitchen knife during a heavy alcohol-fueled dispute on November 27, 2011, causing fatal injuries.
• The victim was left in their shared Cologne apartment and the assault was reported only the following afternoon, by which time he had died.
• Initial inquiries in 2011 failed to establish a viable suspect due to insufficient evidence despite early suspicion of the roommate.
• Renewed investigation leveraged a full re-evaluation of forensic traces alongside new medical expert opinions to secure the arrest.
