John Errol Ferguson, on Death Row for eight murders in Miami-Dade in the 1970s, wont be executed Thursday.
The Florida Department of Corrections initially said last week that Ferguson, 64, would be killed by lethal injection Thursday at 6 p.m., after a two-day delay mandated by the states high court pending last-minute appeals.
But on Monday, the corrections department clarified that an execution date wont be set until after the Florida Supreme Courts stay on the execution expires Thursday afternoon.
Ferguson was convicted of the July 1977 murders of six Carol City residents during a home-invasion robbery. At the time, it was the worst mass murder in Miami-Dade history.
Ferguson, now 64, also was convicted separately of murdering two teenagers, Belinda Worley, a 17-year-old Hialeah High School senior, and Brian Glenfeldt, 17, in January 1978.
On Friday, a Bradford circuit judge said that Ferguson is mentally competent to be executed.
Defense attorneys have maintained for decades that Ferguson is severely mentally ill and his execution would be cruel and unusual punishment.
