Michael Zack was executed in Florida on 3 October 2023 for a murder committed in 1996. Twenty-seven years old at the time of the crime, he was 54 at the time of his death. The courts dismissed appeals that his execution would be unconstitutional based on a new scientific consensus that Fetal Alcohol Syndrome is the functional equivalent of intellectual disability. This was Florida’s sixth execution of the year, its highest annual total since 2014.
