Florida executes James Barnes for 1988 hammer murder after he dismissed appeals

James Barnes was executed in Florida for the 1988 murder of nurse Patricia Miller, whom he killed with a hammer.
Barnes confessed to the crime nearly 20 years later while serving life for killing his wife in 1997.
He pleaded guilty in court and dismissed his appeals, opting for execution instead of further imprisonment.
Barnes claimed to have killed others but was never charged for additional murders.
His death marks the 104th execution in Florida since capital punishment was reinstated in 1976.
