The Torso in the Thames - Almost two weeks later, police found a sheet wrapped around seven candles on the shore of the Thames.

Muti originates in sub-Saharan Africa and includes killing animals and humans for body parts, which are used in an attempt to attract health and good fortune. African experts in ritual killing suggested the orange of the shorts to be a significant colour in Muti.
