Kosta Diamantis Flees While State’s Atty Richard Colangelo Avoids Indictment


In 2020 Chief State’s Attorney Richard J. Colangelo Jr. hired Anastasia Diamantis, the daughter of Kostas Diamantis, who just fled to Greece, as an administrative assistant at $100K a year. Several officials at the Division of Criminal Justice told Colangelo not to hire the daughter of Kostas Diamantis, the deputy secretary of the Office of Policy and Management appointed by Gov Lamont, to avoid an appearance of a conflict of interest, according to a report issued by Stan Twardy, who conducted an independent investigation.
In exchange for hiring Anastasia, Kosta got raises for Colangelo and his employees. In 2022 Colangelo resigned as Chief State’s Attorney, yet was able to keep his generous State Pension, which he collects to this day. In 2025 Colangelo agreed to pay a $7,000.00 fine after he was subjected to discipline by the Office of State Ethics and Justice Andrew McDonald, chair of the Connecticut Criminal Justice Commission, a panel with the authority to fire or discipline State’s attorneys. A slap on the wrist!
Kosta Diamantis was a fully licensed Connecticut attorney when he committed his crimes. After he was found guilty he surrendered his law license. Richard J. Colangelo is still a fully licensed Connecticut attorney. His law license was never suspended, nor was he ever referred for disciplinary action against his law license, unlike New Haven criminal defense attorney Richard Silverstein, who was recently suspended for one year for bouncing a $250 check on his IOLTA account. Silverstein largely represented New Haven’s African American community, and the locals in New Haven were furious at Judge Fischer after the suspension, read the comments in the NHI.
Kosta Diamantis had several co-conspirators in his case who were prosecuted by the DOJ. Richard Colangelo must have known that Kosta was on the take, his criminal behavior was wide ranging and brazen. How could the Chief State’s Attorney not know? Why didn’t Colangelo prosecute Kosta? Colangelo obviously didn’t want to prosecute a fellow co-conspirator. Why didn’t the DOJ prosecute Colangelo? Professional courtesy to a fellow prosecutor? Please! Or does Colangelo know too much? Colangelo was a State’s Attorney for over 30 years. Colangelo must have dirt on everyone in the State, local and possibly even the Federal government. If Colangelo were indicted he would have brought everyone down, Republicans like himself, and Democrats like Diamantis. Hopefully Diamantis will write a blog from Greece exposing the corrupt individuals who govern the “Constitution State.”
