After being sent out to begin deliberations on Monday March 25, following a two-month trial, the six men and six women on the jury returned their conclusions on Wednesday afternoon.
The jury was unable to reach a verdict on Duckenfield on the charge of manslaughter by gross negligence of 95 men, women and children at Hillsborough.
Due to the law in 1989, Duckenfield had not been charged with the manslaughter of Tony Bland, because he died more than a year and a day after the disaster occurred.
Mackrell was found guilty of the charge of breaching the Health and Safety at Work Act 1974 by failing to take reasonable care to have sufficient turnstiles available for the match.
