Steve Smith was executed at 10:29 a.m. Wednesday by lethal injection at the state prison in Lucasville after his pleas for mercy were denied.

The 46-year-old was convicted of aggravated murder in the September 1998 killing of his live-in girlfriend’s daughter, Autumn Carter, in Mansfield.

Smith had tried to get his sentence reduced to life in prison, arguing that he was too drunk to realize his assault was killing Autumn and that he didn’t mean to hurt her.

The Ohio Parole Board and Gov. John Kasich rejected his pleas.

Smith became the 51st inmate put to death in Ohio since it resumed executions in 1999.

Wrangling over the state’s execution procedures has delayed the imposition of capital punishment since July, but a federal judge has initially cleared the state to proceed.

On Wednesday, Mark Wiles died by lethal injection at 10:42 a.m., with the inmate using his final words to express hope his death would bring closure to his victim’s family, but also protesting the death penalty.

“Finally, the state of Ohio should not be in the business of killing its citizens,” Wiles concluded, reading a statement that the warden held over his head. “May God bless us all that fall short.”

It was the 47th execution since Ohio resumed putting inmates to death in 1999, and the state has 11 more executions scheduled, including June, July, September and November.

The next scheduled execution is June 6, when condemned killer Abdul Awkal, 52, is set to die for killing his estranged wife and brother-in-law in 1992, in a room in Cuyahoga County Domestic Relations Court.

Wiles, looking haggard with a sparse, cropped gray beard and shaven head, stared at witnesses for a few moments when he entered the death chamber. A few minutes later, strapped to the gurney and IV lines inserted into his arms, he raised his head and looked at witnesses again.

“Since this needs to be happening, truly I pray that my dying brings some solace and closure to the Klima family and their loved ones,” he said.

The 49-year-old Wiles also thanked his family for their love and support.

As the lethal sedative began flowing, Wiles nodded, appeared to be speaking, swallowed, spoke again, then gasped a few moments later. Wiles’ stomach rose and fell several times and his head moved slightly, then his mouth fell open and he lay still for several minutes before he was pronounced dead.

John Craig, a cousin of Wiles’ victim Mark Klima and a witness of the execution, appeared briefly before reporters to respond to Wiles’ last words.

“It’s my opinion that Mark Wiles gave up his citizenship to Ohio when he murdered my cousin and became an inmate, more or less a condemned man,” Craig said.

Wiles, who dropped his final appeal last week, told the Ohio Parole Board that he wasn’t sure he deserved mercy but he was requesting clemency because he had to. Both the parole board and Gov. John Kasich denied Wiles’ request.

Wiles’ defense team had argued he should be spared because he confessed to the crime, showed remorse and had a good prison record.

Wiles was not “the worst of the worst,” and the parole board showed inconsistency in allowing his execution, his public defenders said in a statement.

Records show that Wiles surprised 15-year-old Mark Klima during a burglary at his family’s farmhouse and stabbed him repeatedly with a kitchen knife until he stopped moving.

Wiles paced back and forth and was emotional and anxious in his last minutes in his cell a few steps from the death chamber, prisons spokeswoman JoEllen Smith said. The inmate spent the night on the phone, listening to the radio and writing letters, Smith said. He and two sisters and a brother-in-law cried during emotional visits Wednesday morning, and he also said the rosary with his spiritual adviser, a Roman Catholic priest who works at Ohio’s death row in Chillicothe.

Wiles did not sleep since arriving at the death house Tuesday morning about 9:45 a.m., Smith said.

Ohio’s most recent execution delays stem from inmates’ lawsuits over how well executioners perform their duties.

The state has a review process in place that allows prisons director Gary Mohr to oversee the details and procedures of the execution policy.

Before the execution, Mohr said he was “absolutely confident” in the state’s ability to carry out the procedure properly.

“We have more documentation on this than anything in my 38 years that I’ve been in this business,” Mohr said. “It’s the most documented execution in the United States of America.”

Prison officials project that if their agency takes a ten percent hit, they’d have to lay off one in six employees, close an unnamed number of prisons, put new inmate housing in areas now reserved for recreation and visitation and perhaps have some inmates sleep in shifts so two inmates would share the same bed.

Assistant Corrections Chief Linda James, warns all those changes would make the remaining prisons not just 32 percent overcrowded, as they are now, but 74 percent over capacity. She says each guard would have to look after more inmates, a recipe for heightened tensions and perhaps a repeat of the deadly 1993 Lucasville prison riot.

“We’d have an inmate to correction officer ratio would increase to 8 to one and that is close to where we were when the Lucasville riot occurred. Right now we have a 6 to one.” Says James

Prisons officials had prepared him for the execution scheduled at ten this morning. Six hours after that, the high court declined to hear the state’s appeal of an order from a Cincinnati-based federal appeals court to delay the execution.

The wait was tough on relatives of the victim who traveled to the prison in Lucasville in southern Ohio.

Biros has acknowledged he killed 22-year-old Tami Engstrom in 1991. Her body was cut up and the parts scattered across eastern Ohio and western Pennsylvania.

The court delay is to allow him to argue with other inmates in a lawsuit saying Ohio’s method of execution by lethal injection is cruel and unusual punishment.
