By Nimi Princewill, CNN(CNN) — French prosecutors are piecing together clues over the death of South Africa’s ambassador to France, Nkosinathi Emmanuel “Nathi” Mthethwa. Early findings, authorities said, suggest Mthethwa had apparently fallen from a high-rise Paris hotel on Monday, hours after sending a “disturbing message” to his wife that he planned to kill himself. An ally of former South African President Jacob Zuma, who faced prosecution on corruption charges, Mthethwa was entangled in probes by several commissions. Mthethwa also faced an ongoing probe that heard allegations by a provincial police commissioner who accused him of attempting to obstruct the prosecution of a former head of South Africa’s Crime Intelligence Services who was being investigated for corruption. ‘Evidently suspicious circumstances’South African President Cyril Ramaphosa said Mthethwa’s life “ended prematurely and traumatically” in a statement that praised his service to the nation.
