Attorneys for a condemned killer facing execution this week in Texas are insisting his punishment should be stopped because he risks the same ordeal experienced recently by an Oklahoma inmate whose lethal injection was disrupted.
Robert Campbell's scheduled Tuesday evening execution in Huntsville would be the first nationally since Clayton Lockett's bungled punishment April 29. Lockett died of an apparent heart attack after Oklahoma prison officials aborted his execution following the failure of an intravenous line carrying the deadly drugs.
Lawyers for Campbell say they must know the source of the drug used in Texas. Prison officials have refused.
Attorneys also are arguing in appeals that Campbell's mentally impaired and ineligible for execution.
Campbell was convicted of the 1991 abduction and fatal shooting of a 20-year-old Houston woman, Alexandra Rendon.
