One small part of themystery is solved. Joseph di Mambro, the financial mastermind behind the cultwhose 53 members were found dead in Switzerland and Canada last week, did,indeed, perish with the others. Investigators say di Mambro's body was found inthe rubble of three chalets destroyed by fire in a Swiss village. But thewhereabouts of Luc Jouret, a charismatic Belgian doctor who apparently headedthe cult, are still unknown and Swiss investigators have a warrant out for hisarrest. All the people found dead were either Swiss, French or Canadian and hadbeen killed or committed suicide.
