Burge was found guilty on all counts of an indictment charging him with perjury and obstruction of justice for lying in a 2003 civil case about his knowledge of the torture of suspects.
Deliberations began Thursday following a five-week trial with testimony from five convicted felons, including two convicted of killing police officers. The accusers said they were subjected to beatings, suffocations and games of Russian roulette.
Burge, 62, could be sentenced to as much as 45 years in prison.
Burge also faces another civil suit, this one filed by Darrell Cannon, who said Burge's subordinates staged a mock execution and shocked him with a cattle prod in the genitals to get him to confess to murder in 1983.
Several other alleged victims have been exonerated in recent years and have indicated they too plan to sue Burge, the Chicago Tribune reported.
