The state corrections department said Wednesday the execution of Andrew Grant DeYoung would be rescheduled for Thursday at 7 p.m.
Attorney General Sam Olens would not say why the execution was rescheduled.
The Georgia Supreme Court earlier upheld a request by another death row inmate to videotape DeYoung’s execution as part of his challenge to the state’s execution procedure.
Experts say it would be the first known recording of an execution since 1992. In that California case, the state’s method of execution using lethal gas was being challenged. The tape was later destroyed.
