The trial of Randall Paul Earp, a 22-year-old Gaithersburg man accused in the stabbing of a man in a violent Halloween street brawl in Rockville last year, ended in a mistrial last night after a Montgomery County Circuit Court Jury failed to reach a verdict.

The mistrial came nearly three months after the man Earp was accused of stabbing, Michael Lawrence, 22, died of bone cancer. On the first day of the trial, Assistant Montgomery County State's Attorney John McCarthy played a videotaped record of testimony Lawrence made from his deathbed at the National Institutes of Health.

The jury deliberated 11 hours before sending word to Judge William Cave that it could not agree on a verdict. Earp was charged with attempted first-degree murder, attempted second-degree murder and assault with intent to maim. Prosecutors did not say whether they will retry the case.

According to the testimony of prosecution witnesses, Earp and Lawrence were at a party in the 4900 block of Randolph Road when a free-for-all erupted and two men were struck by a pickup truck.

When Lawrence went to investigate and confronted the driver of the truck, Earp stabbed him in the back and hand, witnesses testified.
