Suicide, Corruption Probe Rattle Peru’s Political Class

Peru’s former presidents are falling one by one and the Andean nation’s political class is teetering and spooked.

Opposition officials say Jose Domingo Perez, who is the face of the corruption investigation that’s implicated four former chief executives and dozens of lesser officials, is hounding their leaders. On Wednesday, the team to which Perez belongs charged Ollanta Humala and his wife with money laundering. Last month, Humala’s predecessor killed himself as police arrived and another ex-president was placed under house arrest.
