NASHVILLE, Tenn. — Christa Pike has begun walking with assistance and eating again, her attorneys said Thursday, a week after Tennessee’s attempt to execute her with lethal drugs failed and left her hospitalized. Pike, 50, regained consciousness Tuesday and was able to speak, according to her legal team. Her first steps the next day were limited, and she still needed help walking Thursday. She is also regaining movement in her arms and was able to eat for the first time, her attorneys said. Pike’s lawyers said she had been unconscious and on a ventilator during the first days of her hospitalization. They said she continues to have difficulty with concentration and memory, and doctors have not yet been able to assess possible long-term effects. “Significant questions remain about the long-term effects of what she endured,” her attorneys said in a statement, describing the attempt as a source of profound psychological trauma as well as physical pain and uncertainty. The execution attempt took place Sept. 30. Pike survived two doses of pentobarbital, and her lawyers said her arms were burned and blistered. Medical and lethal-injection experts have raised the possibility that an improperly placed IV caused the drug to enter tissue rather than her bloodstream. State officials have not publicly explained what happened. Pike was sentenced to death for the 1995 beating and stabbing death of her classmate, Colleen Slemmer. As the execution began, Pike was asked whether she had a final statement and said she was at peace. About five minutes later, she raised her head and said her arm hurt. She later appeared to lose consciousness and was heard breathing heavily before media witnesses were escorted out of the witness room. An ambulance took her to a hospital. A Nashville judge on Wednesday ordered the Tennessee Department of Correction to preserve evidence related to the failed execution. Gov. Bill Lee has postponed the state’s only other execution scheduled for this year and ordered a review. The state’s prison chief resigned after the attempt. It remains unclear whether Tennessee will try to execute Pike again. Her attorneys say they will ask Lee, a Republican, to commute her sentence to life in prison without parole. They said she should not face another execution attempt.
