The Mangano-Venditto federal corruption trial is now focused on the former county executive's wife.

The lead FBI agent on the case took the stand today in Central Islip. Special Agent Laura Spence told the court that the wife of County Executive Ed Mangano gave inconsistent answers when questioned by authorities. 

Linda Mangano was grilled about allegedly having a "no-show" job with restaurateur Harendra Singh. Prosecutors say it was one of the bribes Singh offered Ed Mangano and former Town of Oyster Bay Supervisor John Venditto.

Linda Mangano is accused of obstructing justice and making false statements to the FBI.

The prosecution’s star witness restaurateur Harendra Singh has already testified that he gave Linda Mangano a "no-show" job that paid her $100,000 a year.

Meanwhile, Newsday reports that Singh filed for Chapter 13 bankruptcy protection back in April. According to Newsday, Singh owes banks more than $5 million in interest and fees.
