Former Connecticut Budget Official Sentenced to Seven Years for Corruption

Kosta Diamantis, Connecticut’s former deputy budget director and one-time chief of school construction funding, was sentenced in absentia on 30 September 2026 to seven years in prison followed by three years of supervised release, after being convicted on multiple federal corruption counts, according to Connecticut public radio station WSHU and other local outlets.

Convicted After Fleeing to Greece

Diamantis was convicted last year on 21 counts including bribery, extortion, conspiracy and making false statements to investigators, reports said. He had originally been due to be sentenced two weeks earlier but failed to appear in court; prosecutors and the presiding judge later learned he had used a Greek passport he had been instructed to relinquish to flee to Greece. The court proceeded to sentence him in his absence.

Part of a Pattern of State Corruption Cases

Local reporting noted that Diamantis now joins a list of Connecticut officials convicted on bribery-related charges in recent years, underscoring recurring scrutiny of how state school-construction funding and related contracts have been awarded and overseen. His case drew particular attention in the state because of his flight abroad, which added an international dimension to what had already been a closely watched prosecution. As deputy budget director, Diamantis had overseen hundreds of millions of dollars in state funding for school construction projects, a position prosecutors said gave him leverage to solicit payments from contractors seeking approval for their projects.

Why It Matters

The case highlights ongoing vulnerabilities in the oversight of large public infrastructure and construction budgets at the state level, where officials with discretion over contracting decisions can face strong temptations absent robust internal controls. Diamantis’s decision to flee the country before sentencing, and the court’s willingness to proceed without him, also signals how US courts are treating fugitive defendants in corruption cases, an approach likely to influence future prosecutions.
