The Brooklyn Democratic Party’s former leader, Clarence Norman Jr., was convicted yesterday of stealing a $5,000 check from his re-election campaign, a felony that could land him in prison for up to seven years.

The guilty verdict comes just two and a half months after Norman was convicted on three felony charges for soliciting illegal campaign contributions. The Brooklyn district attorney, Charles Hynes, has another two cases pending against him.

Handed down after about a week of deliberations, the verdict is another triumph for the district attorney’s office, which is said to be pursuing Norman aggressively to help crack a larger judicial corruption case in the borough.

With Norman now on the hook for two convictions and the prospect of serious prison time, some said yesterday that the fallen party boss might be more inclined to tell prosecutors if he knows anything about how judgeships were sold and who was involved. In the past, he has said he would not cooperate because he didn’t know anything.

Norman, who was stripped of the Assembly seat he held in Crown Heights after his first conviction, posted $100,000 bail yesterday. His sentencing is scheduled for January 10.

His lawyer, Edward Rappaport, told The New York Sun last night that he was “disappointed” and “upset” with the verdict. “I guess we now have lost sight of the fact that it is the prosecution that’s supposed to prove that someone is guilty not the defendant who has to prove he’s innocent,” Mr. Rappaport said during a phone interview.

Mr. Rappaport said the case was unfounded. “I still don’t think that the case was warranted and I truly don’t think that he’s guilty,” he said.

When asked how Norman had responded to the conviction, he said: “He’s a very religious man and I think he’s doing fine.”

The lead prosecutor in the case, Michael Vecchinone said: “The jury saw what we saw. The evidence in our opinion was clear and overwhelming and hence the verdict,” News 12 Brooklyn reported.

During the trial, which was held in state Supreme Court in Brooklyn, Mr. Vecchione painted Norman as a savvy politician who knowingly flouted the law. Norman claimed he used poor judgment but had done nothing wrong.

The case centered on a $5,000 check written out to Norman’s campaign that prosecutors said Norman illegally deposited into his personal bank account. Norman’s defense was that he paid Assemblywoman Diane Gordon the money from his personal account to pay workers on the day of the Democratic mayoral primary in 2001 and was simply reimbursing himself.

Ms. Gordon, who was billed as his star witness, invoked the Fifth Amendment when she was called to testify.

Yesterday, Mr. Rappaport said he had heard that some of the jurors felt they needed to hear from her. A Brooklyn district leader, JoAnne Simon, one of the self-described “reformers” in the party, said it was a “sad” situation.

When asked whether she thought Norman would try to cut a deal with prosecutors, she said: “I don’t know that he will be more apt to talk. When you look at what the consequences are of talking he may or may not choose to do that and I don’t know what Clarence knows.”

Norman still faces perhaps the most serious of the charges: He and the executive director of the Brooklyn Democratic Party, Jeffrey Feldman, are charged with extortion and coercion.
