DALLAS, Texas (CNN) - Texas Gov. Rick Perry has shaken up a state commission that is probing whether a man executed in 2004 belonged on death row. Perry's move forces the commission to delay a scheduled hearing on the case.
The governor acted two days before the commission was to hear from an expert who has cast doubt about the quality of the arson investigation that helped convict Cameron Todd Willingham of murder in the deaths of his three daughters in a fire at their home.
Death-penalty opponents say a thorough review of the Willingham case may force Texas to admit that it executed an innocent man. The Texas governor and others, however, say they remain convinced of Willingham's guilt.
Perry replaced the chairman of the Texas Forensic Science Commission and declined to reappoint two commission members. The commission was to hear testimony Friday from Craig Beyler, an arson investigation expert. He wrote the latest of three reports critical of the testimony that helped prosecutors convict Willingham of murder in 1992.
The governor's office told CNN the moves were a routine replacement of members whose terms had expired.
