Jurors in the Dewey & LeBoeuf criminal trial stuck it out for one more day of deliberations on Wednesday, laboring uneventfully even as the months-long trial threatened to end in a mistrial.

Wednesday was the 18th full day of deliberations in the trial of Dewey & LeBoeuf chairman Steven Davis, former executive director Stephen DiCarmine and former chief financial officer Joel Sanders. Over nearly four weeks of deliberations, the Manhattan jury has twice complained of deadlock—and twice delivered partial verdicts that cleared Dewey’s former leaders of relatively minor charges.
