Lucasville, Ohio: The children of convicted murderer Dennis McGuire, whose execution by a new lethal injection took longer and seemed to be more painful than expected, plan to sue Ohio to block further use of this method. .
Lawyer Jon Paul Rion, who represents the children who witnessed Thursday's execution at the Southern Ohio Correctional Facility in Lucasville, said the suit was expected to be filed next week in federal court.
"We believe what happened yesterday was cruel and unusual punishment," he said.
"I can't imagine a more drastic way to die than to be tied to a board and deprived of oxygen for half an hour or 25 minutes."
Mr Rion said that the death violated constitutional protections against cruel and unusual punishment and that the family would be seeking a moratorium on executions until a more humane method can be devised.
"We would like this protocol and procedure to be forever banned and that these drugs not be used on humans in this fashion ever."
McGuire was convicted in the 1989 rape and murder of Joy Stewart, a 22-year-old pregnant woman.
McGuire's son, also named Dennis, described to reporters how he saw his father die.
"Shortly after the warden buttoned his jacket to signal the start of the execution, my father began gasping and struggling to breathe. I watched his stomach heave. I watched him try to sit up against the straps on the gurney. I watched him repeatedly clench his fist. It appeared to me he was fighting for his life but suffocating," Mr McGuire said.
"The agony and terror of watching my father suffocate to death lasted more than 19 minutes. It was the most awful moment in my life to witness my father's execution. I can't think of any other way to describe it than torture."
McGuire's execution has reignited the debate over how society can carry out a death sentence that does not violate constitutional protections against cruelty. The issue has been complicated as states have searched for a new protocol after companies that make drugs used in lethal injections pulled them off the market under pressure from death penalty opponents.
On Thursday, McGuire was given midazolam, a sedative, and hydromorphone, derived from morphine, by intravenous injection. It was the first time any state had used that particular protocol. Reports from witnesses at the execution have varied about the times involved, but all agreed that McGuire made noises and that the execution took longer than expected.
Mr Rion said that the entire procedure took about 25 minutes from when the drugs were first injected. Nothing happened for the first few minutes but "there were at least 19 minutes of demonstrable pain and suffering observed" by the family, he said.
