We now know why the fed is investigating the city of Springfield and an Agawam construction firm. According to a story in The Springfield Republican the city paid Zielinski Brothers of Agawam some 4 point 6 million dollars since 2009. It was believed to be a little more than 117 thousand dollars. So far this fiscal year the city solicitor says that the company has been paid 800 thousand dollars. The company hasn't commented. The fed does not comment.
