The jury in Jon Burge's trial has gone home for the weekend, not reaching a verdict after deliberations had gone into a second day.
Burge is accused of perjury and obstruction of justice, covering up years of torture of criminal suspects by Chicago police.
During trial prosecutors presented the testimony of 5 men Burge and his officers allegedly tortured from 1973 to 1985. The closing arguments were Thursday.
If convicted Burge could be sentenced to 20 years for each of two counts of obstruction of justice, five years for perjury and a $250,000 fine on each count.
