Florida has carried out the state’s first execution since a botched lethal injection procedure prompted a moratorium and an investigation.

Gov. Charlie Crist’s office says Mark Dean Schwab died by lethal injection at 6:15 p.m. Tuesday.

Schwab was convicted of kidnapping, raping and killing an 11-year-old Junny Rios-Martinez in 1991.

The execution is the initial test of Florida’s new lethal injection procedure, which was instituted after Angel Diaz was put to death in December 2006. Needles to inject the deadly chemicals into Diaz missed their mark and he suffered burns and extreme pain.

Schwab unsuccessfully challenged Florida’s new procedure in court.
