Florida has executed the convicted ringleader of a 1993 home-invasion robbery that ended with the murder of a Pensacola banker and the rape of his wife.

Johnny Shane Kormondy was pronounced dead at 8:16 p.m. Thursday at Florida State Prison, shortly after the lethal injection was administered. The execution was delayed by two hours by a late appeal to the U.S. Supreme Court that was eventually denied.

The 42-year-old Kormondy and two associates were convicted of forcing their way into the Pensacola home of Gary and Cecilia McAdams in 1993. Gary was fatally shot, and Cecilia raped repeatedly.

The two other men were convicted and sentenced to life in prison.

Kormondy is the 21st inmate executed under Gov. Rick Scott. The same number of prisoners was put to death under former Gov. Jeb Bush. The death penalty was reinstated in Florida in 1979.
