A mistrial was declared in Bill Cosby's sexual-assault trial Saturday, after jurors reported that they were hopelessly deadlocked.

The panel had first reported an impasse Thursday, in their fourth day of deliberations. The seven men and five women from Allegheny County were then told to keep talking.

In total, the Cosby jurors deliberated for about 52 hours.

No two trials — or jury panels — are ever identical, making comparisons unrealistic. But here's a look at how long jurors have spent deliberating other high-profile trials in Pennsylvania and across the country:

O.J. SIMPSON: 3.5 hours

It took less than four hours for a Los Angeles County jury to acquit Simpson of the murder of his ex-wife and Ronald Goldman in 1995, after an eight-month trial. Jurors later cited their lengthy sequestration as part of the reason they were so eager to quickly render a verdict.


Jurors in Santa Barbara County, Calif., debated for 32 hours over seven days in 2005 before clearing the pop icon of 10 counts of molestation, intoxicating a minor and conspiracy to commit kidnapping. The trial lasted three-and-a-half months.


After a four-month trial, jurors needed five days to decide to convict the former state senator from Philadelphia of all 137 charges he faced in his 2009 corruption trial.


A worldwide spotlight focused on tiny Bellefonte, Centre County, for the 2012 eight-day trial of the former Pennsylvania State University assistant football coach. Jurors spent two days deliberating before convicting him of 45 counts of child-sex abuse and acquitting him on three counts.

MSGR. WILLIAM LYNN: 12 1/2 days

The three-month trial of the former secretary of clergy for the Philadelphia archdiocese marked the first time a church official was prosecuted for concealing or covering up clergy sex-abuse. The Philadelphia jury convicted Lynn of a single count of child endangerment but acquitted him on two other counts. It also deadlocked on attempted rape and child endangerment charges against a co-defendant priest in the case.


After 10 weeks of testimony in 2015, a Massachusetts jury spent about a week in talks before convicting the former star tight end for the New England Patriots of murdering Odin Lloyd, a former linebacker for a semi-professional football team. Hernandez was found dead in his prison cell earlier this year.

CHAKA FATTAH: 14 hours

The former Democratic congressman was found guilty of all 22 counts he faced for racketeering and bribery after 2 ½ days of deliberations. The 2016 trial lasted four weeks. He began his 10-year prison term in January.

KATHLEEN KANE: 4.5 hours

Facing trial in the same courthouse as Cosby, the former Pennsylvania Attorney General was convicted last August of two counts of perjury and seven misdemeanor counts of obstruction of justice after a weeklong trial. Jurors concluded that Kane had orchestrated an illegal leak of secret grand jury documents to a reporter in a bid to embarrass a political rival and later lied about it under oath.
