Two members of the federal jury that found Maryland politicians Clarence M. Mitchell III and Michael B. Mitchell guilty of corruption charges said yesterday that the 12-member jury was very close to finding the brothers guilty of broader conspiracy charges.

"There was the smallest, slightest doubt . . . in the beginning that they planned this," said juror Mary Lou Crummitt. "The rest was just black and white. There was no one {on the jury} who said, 'No, they are not guilty.' "

The Mitchells were convicted Friday in Baltimore on charges of accepting $50,000 to stop a congressional investigation of the scandal-tinged Wedtech Corp. They also were found guilty on wire-fraud charges but were acquitted of the charge that they were involved in a conspiracy to halt the probe.

Members of a prominent black political family in Baltimore, they were charged with taking money from Wedtech officials in 1984 and 1985 in exchange for blocking a probe of company activities.

Federal prosecutors tried to prove that the Mitchell brothers planned to exploit ties to their uncle, former representative Parren J. Mitchell, who then headed the House Small Business Committee. At the time, the committee was looking into allegations that Wedtech, a minority-owned federal contractor, had received preferential treatment in obtaining millions of dollars in no-bid military contracts.

"If one of those witnesses would have said that Michael had said he could stop the investigation, then {a guilty verdict on the conspiracy charge} would have been unanimous," Crummitt said.

Prosecutors and defense attorneys agreed that Parren Mitchell was never approached by his nephews.

Clarence Mitchell, a former state senator, could be sentenced to a maximum of 10 years in prison, and Michael Mitchell, who now serves in the state Senate, to 15 years. However, if they had been found guilty of the conspiracy charge, they could have faced an additional five years in prison.

Crummitt, who works for the National Geographic Society's Educational Services in Gaithersburg, said that despite the overwhelming evidence on charges of wire fraud, the prosecutors were unable to offer enough proof of a conspiracy that would have removed "that slight question" from her mind.

By Crummitt's estimation, the jury "took five or six votes on each count" during the 11 1/2-hour deliberation, which ended Friday evening.

Juror Elizabeth Delacruz of Bethesda said that, based on a contract between the Mitchells and Wedtech dated Oct. 24, 1984, and other evidence presented by the Mitchells' attorneys, the jury believed that the pair agreed to be lobbyists for the New York-based company without at first realizing that it was so deeply in trouble.

Delacruz felt that the Mitchells' "crime was not in getting involved, but in staying involved."

Each juror said it appeared that greed played a big role in the Mitchells' involvement with Wedtech.
