Dennis McGuire's family plan to sue state of Ohio after long execution
Fatal injection using cocktail of drugs took more than 20 minutes to kill rapist and murderer
A condemned man appeared to gasp several times and took an unusually long time to die - more than 20 minutes - in an execution carried out on Thursday with a combination of drugs never before tried in the US.
Dennis McGuire's lawyer Allen Bohnert called the convicted killer's death "a failed, agonising experiment" and added: "The people of the state of Ohio should be appalled at what was done here today in their names."
A lawyer for McGuire's family said it plans to sue the state over what happened.
McGuire's lawyers had attempted last week to block his execution, arguing that the untried method could lead to a medical phenomenon known as "air hunger" and could cause him to suffer "agony and terror" while struggling to catch his breath.
McGuire, 53, made loud snorting noises during one of the longest executions since Ohio resumed capital punishment in 1999. Nearly 25 minutes passed between the time the lethal drugs began flowing and McGuire was pronounced dead at 10.53am.
Executions under the old method were typically much shorter and did not cause the kind of sounds McGuire made.
An Ohio prisons spokeswoman had no comment on how the execution went but said a review will be conducted as usual.
Prison officials gave intravenous doses of two drugs, the sedative midazolam and the painkiller hydromorphone, to put McGuire to death for the 1989 rape and fatal stabbing of a pregnant newlywed, Joy Stewart.
The method was adopted after supplies of a previously used drug dried up because the manufacturer declared it off limits for capital punishment.
The execution is certain to launch a new round of federal lawsuits over Ohio's injection procedure. The state has five more executions scheduled this year, with the next one to come on February 19.
McGuire's lawyer called on Republican Governor John Kasich to impose a moratorium on future executions.
What was particularly unusual on Thursday was the five minutes or so that McGuire lay motionless on the gurney after the drugs began flowing, followed by a sudden snort and then more than 10 minutes of irregular breathing and gasping. Normally, movement comes at the beginning and is followed by inactivity.
"Oh, my God," his daughter, Amber McGuire, said as she watched his final moments.
Dayton defence lawyer Jon Paul Rion said the family is deeply disturbed by McGuire's execution, which it believes violated his constitutional rights. "All citizens have a right to expect that they will not be treated or punished in a cruel and unusual way," Rion said. "Today's actions violated that constitutional expectation."
McGuire, strapped to the gurney as members of the execution team inserted intravenous needles into his arms, spoke some.
McGuire thanked Stewart's family members, who witnessed the execution, for their "kind words" in a letter he apparently received from them. "I'm going to heaven. I'll see you there when you come," he said.
