ATHENS — Prosecutors said Wednesday that Jim Donnan lured his friends into a fraudulent investment scheme because he was blinded by the enormous amount of money he could make, while defense attorneys argued the former University of Georgia football coach was duped and thought he was presenting them with a great opportunity. Donnan is on trial in federal court on charges including conspiracy, wire fraud, mail fraud and money laundering. Jurors deliberated about three hours Wednesday afternoon without reaching a verdict and were set to resume deliberations Thursday morning.
