In 2008 a man who committed suicide was implicated as the series of murders ended in 2007, but the connection could not be conclusively proven.
Body parts were found in June and July 2007 in the Khomas Region along the B1 in the greater Windhoek area between Rehoboth and Okahandja.
In October 2007, investigations were helped by three senior serial murder detectives from the Republic of South Africa.
In addition, all victims' body parts showed signs of freezing or refrigeration, suggesting that they were in some sort of cold storage.
In August 2007, the German citizen Heinz Knierim was arrested because he was suspected of having raped a 29-year-old Namibian near Windhoek the previous month.
In July 2007, women from Windhoek, Rehoboth and Tsumis Park published a joint open letter to the B1 Butcher to provide information on the still missing body parts for decent burial of the murder victims.
In 2010, a human head and an arm were discovered on a farm in Rehoboth, raising fear that the Butcher might be active again.
A connection to the murders of the B1 Butcher in this was, however, not considered likely because it did not show many of the previous similarities: The body parts were not found near a highway, and were burnt instead of frozen.
