Sid Hawk Byrd is confined in the Coffield Unit of the Texas Department of Criminal Justice, serving a life sentence for aggravated assault on a public servant and unlawful possession of a firearm. Jason Clark, a spokesman for TDCJ, confirms that Byrd has been in segregation since May 2003, sent there because of repeated escape attempts. Clark did not know if Byrd had been placed in segregation previously, and how much total time Byrd has spent in isolation. Clark said it is conceivable that inmates could spend up to 20 years in isolation if they fall into one of the categories for which isolation is used—gang members, security risks, or inmates who pose a threat to a guard or another inmate. Clark also confirmed that an inmate named Jason Rabago committed suicide in Byrd's unit in February 2007. Clark confirmed some of the conditions in segregation described by Byrd, including that guards wear Kevlar vests and that guard extraction teams use teargas and Mace before entering cells to remove inmates.
