Sumanto (born Purbalingga, Central Java 3 March 1972) is a cannibal from Indonesia. In early 2003, he stole the dead body of an eighty-one year old woman who had been buried for less than 24 hours before he ate her. He believes that this action will give him supernatural power.
Sumanto's belief is based on local mysticism. Experts believe that Sumanto suffers from mental illness. Sumanto is now placed in a pesantren. His action was seen as "disturbing to the community".
