According to ABC News, McMichael was moved from Georgia Diagnostic and Classification State Prison to Augusta State Medical Prison.
The medical prison sometimes serves as a holding facility for inmates as they await transfer to a new facility, but also "houses severe medical cases," offering "centralized acute, specialized medical and Level IV Mental Health services for male and female offenders primarily as transient," per the Georgia Department of Corrections.
In a statement, Joan Heath, Georgia DOC Office of Public Affairs director, told ABC News that all offenders who enter the Ga Diagnostic & Classification Prison are moved to their permanent housing assignment after an individual diagnostic evaluation.
It's unclear if McMichael's transfer to medical prison was due to his health condition.
"Specific details of diagnostic evaluations are part of an offender's institutional file and are not subject to disclosure," Heath said.
A.J. Balbo, McMichael's attorney, cited the convicted killer's age and health issues, including a stroke and depression, after he was found guilty of federal hate crime and sentenced in August to life in prison.
McMichael and his son Travis McMichael, the man who fatally shot Arbery, were also sentenced to life without parole in November 2021. Neighbor, William "Roddie" Bryan was sentenced to life with the possibility of parole in connection to Arbery's killing.
