Florida will train execution teams better and will require some members to be medical professionals in an attempt to avoid repeats of a botched December execution, according to documents made public Friday.
The changes are the second the state has made since it took 34 minutes - twice as long as normal - for a lethal injection to kill convicted murderer Angel Diaz, 55. Needles had been pushed through his veins into the flesh of his arms, reducing the effectiveness of the three chemicals used in executions.
The first round of changes included better training and communication, a clear chain of command and additional staffing.
But a judge questioned whether those revisions did enough to prevent "pain or lingering death."
Circuit Judge Carven D. Angel, who is hearing a challenge to the lethal injection procedures on behalf of death row inmate Ian Deco Lightbourne, last month suspended hearings until the state again updated its procedures.
The most contentious suggestion in the first set of changes was for prison officials to explore newer chemicals and evaluate whether a paralytic drug should be administered.
The second set contains no change in the drugs. That will remain a key objection, said Neal Dupree, whose office represents death row inmates in the southern third of the state.
Dupree specifically objects to pancronium bromide because paralysis makes it impossible for inmates to indicate they are in pain.
Executions were banned in Florida after Diaz's death. Gov. Charlie Crist lifted the moratorium last month when he signed a death warrant for Mark Dean Schwab, 38. Schwab raped and killed an 11-year-old boy in Brevard County.
