LUCASVILLE, Ohio 
    (AP) -- An attorney for the family of a killer whose Ohio execution 
by lethal injection was marked by several minutes of unprecedented 
gasping and unusual sounds plans to sue the state over what happened.
 
Dayton
 defense lawyer John Paul Rion says Dennis McGuire's family is deeply 
disturbed by his execution and believes it violated his constitutional 
rights.
Rion is a member of a state Supreme 
Court panel examining possible changes to Ohio's death penalty law. 
He 
said Thursday all citizens have a right to expect they won't be punished
 in a cruel and unusual fashion.
McGuire was 
executed Thursday for raping and killing a pregnant woman in 1989. He 
took nearly 25 minutes to die, an unusually long time based on prior 
executions.
THIS IS A BREAKING NEWS UPDATE. Check back soon for further information. AP's earlier story is below.
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 
Thursday with a combination of drugs never before tried in the U.S.
Dennis
 McGuire's attorney Allen Bohnert called the convicted killer's death "a
 failed, agonizing experiment" 
and added: "The people of the state of 
Ohio should be appalled at what was done here today in their names."
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 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 10:53 
a.m.
Executions under the old method were typically much shorter and did not cause the kind of sounds McGuire made.
Ohio prisons spokeswoman JoEllen Smith 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 Feb. 19.
What
 was particularly unusual 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 her father's final moments.
In
 pressing for the execution to go ahead, Assistant Ohio Attorney General
 Thomas Madden had argued that while the U.S. Constitution bans cruel 
and unusual punishment, "you're not entitled to a pain-free execution."
U.S.
 District Judge Gregory Frost sided with the state. But at the request 
of McGuire's lawyers, he ordered officials to photograph and preserve 
the drug vials, packaging and syringes.
The 
selection of drugs for use in executions in the U.S. involves more than 
just considerations of effectiveness. It is complicated by the politics 
of the death penalty, questions of medical ethics and the constitutional
 protection against cruel and unusual punishment.
In
 Ohio's case, the state in recent years used pentobarbital - a form of 
which is used to put down cats and dogs. But the state's supply ran out 
after the manufacturer refused to allow its use in executions.
Some
 executions with pentobarbital ran into problems, but they involved 
difficulties inserting the needle, not trouble with the effectiveness of
 the drug itself.
A few minutes before McGuire
 was put to death, Ohio prison director Gary Mohr said he believed the 
state's planning would produce "a humane, dignified execution" 
consistent with the law.
Strapped to a gurney 
in the death chamber, 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.
Stewart's
 slaying went unsolved for 10 months until McGuire, jailed on an 
unrelated assault and hoping to improve his legal situation, told 
investigators he had information about the death. His attempts to pin 
the crime on his brother-in-law quickly unraveled, and he was accused of
 the killing.
More than a decade later, DNA 
evidence confirmed McGuire's guilt, and he acknowledged his 
responsibility in a letter to Gov. John Kasich last month.
The
 death row inmate's lawyers argued McGuire was mentally, physically and 
sexually abused as a child and had impaired brain function that made him
 prone to act impulsively.
"We have forgiven 
him, but that does not negate the need for him to pay for his actions," 
Stewart's family said in a statement after the execution.
