HOUSTON --Gov. Rick Perry is pledging to help obtain compensation for a man denied the payment after he was exonerated of his capital murder conviction. The Texas Comptroller's Office had denied compensation to Anthony Graves, even though prosecutors declared him innocent of the murder for which he served 18 years in prison. Perry told the Houston Chronicle on Wednesday that Graves' conviction had been a "great miscarriage of justice" and pledged to help him obtain the compensation denied him. Graves spent nearly half his adult life behind bars before prosecutors determined last October that he wasn't involved in the 1992 slayings of six members of a family in Burleson County, about 100 miles northwest of Houston.
