Jurors in the racketeering trial of reputed crime boss James "Whitey" Bulger were sent home for the weekend after a fourth day of deliberations ended with no verdict.

The day was highlighted by an angry spat between prosecution and defense lawyers over a comment prosecutors said showed a defense lawyer is trying to influence jurors.

On Friday, prosecutor Brian Kelly asked the judge to admonish attorney J.W. Carney Jr., citing comments he made to reporters praising the jury's diligence. Kelly called the comments "an obvious attempt" to influence the panel.

Carney says he was making a "neutral" comment. Judge Denise Casper did not take any immediate action.

The 83-year-old Bulger is charged in a sweeping racketeering indictment with playing a role in 19 killings. He was one of the nation's most wanted fugitives until being captured in Santa Monica, Calif., in 2011.

Jurors in the case are not sequestered.
