A former Branford firefighter convicted of federal embezzlement charges has filed a state complaint alleging the city illegally rescinded a conditional employment offer after learning about his past criminal charges. A Commission on Human Rights and Opportunities complaint dated March 2 and filed by Andrew Konspore said the City of New Haven violated state statute when it withdrew its conditional offer of employment in September. Konspore alleges this was done despite his having proper certification and ranking highly in his application for firefighter. He pleaded guilty to charges in 2006 that were unrelated to his work as a Branford firefighter.
