HOUSTON (AP) - Texas. Gov. Rick Perry says the capital murder conviction of a man exonerated after 18 years in prison was a "great miscarriage of justice."

According to the Houston Chronicle, Perry said during an appearance Tuesday that he recognizes the effort to win compensation for Anthony Graves.

The Texas Comptroller's Office has denied compensation to the 45-year-old Graves, even though prosecutors declared him innocent last October of the 1992 slayings of six members of a family in Burleson County, about 100 miles northwest of Houston.

The only evidence tying Graves to the killings came from his co-defendant, Robert Earl Carter, who absolved Graves shortly before he was executed 10 years ago.

Asked about Perry's comments, a spokeswoman said Wednesday night that "We see that there has been a miscarriage of justice."
