Overview

• Jurors in Bridgeport heard opening presentations as Konstantinos “Kosta” Diamantis, a former deputy budget director and school construction leader, faces 22 federal counts and maintains his not‑guilty plea.
• John Duffy, a former Acranom Masonry executive and Diamantis’ ex–brother‑in‑law, testified that cash bribes were delivered at a Hartford restaurant bathroom, a Dunkin’ near state offices, and at Diamantis’ home.
• Prosecutors previewed messages in which Diamantis discussed a 5% cut and pressed for payments, plus a voicemail referencing urgent needs tied to his daughter’s tuition and wedding expenses.
• Duffy said Diamantis used his influence on projects including Hartford’s Weaver High School and Tolland’s Birch Grove Elementary, and he acknowledged initially lying to investigators before admitting the payments.
• Defense attorney Norm Pattis declined an opening statement, signaled plans to call Gov. Ned Lamont, and indicated Diamantis may testify as the trial proceeds through much of October.
