Florida ? Florida on Tuesday carried out its first execution since a botched lethal injection procedure prompted the state to revamp the way it conducts capital punishment.

Mark Dean Schwab, who was convicted of kidnapping, raping and killing an 11-year-old boy, died at 6:15 p.m.

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

It took 34 minutes for Diaz to die, more than twice the normal time. Schwab’s execution started at 6:03 p.m. and lasted 12 minutes.
