A month after jury deliberations began in the case against three Dewey & LeBoeuf executives, jurors left court Friday without a complete verdict. But deliberations appeared to have been revived with the jury’s request to hear testimony from four witnesses.

The jurors Friday asked for a readback of testimony related to Dewey’s 2010 refinancing and private bond offering with insurance companies, indicating they were possibly considering the charges against the Dewey leaders for securities fraud under the Martin Act or first-degree grand larceny, the most serious charges in the indictment.
