In Florida, opponents of the death penalty have filed a petition to halt lethal injection after an execution of a death row prisoner took more than half an hour. The prisoner, murder convict Angel Diaz, was killed Wednesday by a three-drug cocktail used in Florida and other death penalty states. Witnesses reported Diaz appeared to suffer and had to have the drugs administered twice. Petitioners are asking the state Supreme Court to halt lethal injunction and order an autopsy on Diaz’s body. Diaz is a native of Puerto Rico. He was executed over the objections of Puerto Rican officials including Governor Acevedo Vila and Senate President Kenneth McClintock.
