ATLANTA (AP) -- The lawyer for a Georgia man set to become the
state's 23rd inmate to be put to death by lethal injection has petitioned the state and U.S. Supreme Court to spare his client's life.
Mark Howard McClain is scheduled to be executed on Tuesday at 7 p.m.
His attorney, Brian Kammer of the Georgia Resource Center, says he has asked the U.S. Supreme Court to order a lower court review of the case.
McClain was convicted of murdering 28-year-old Kevin Brown during a robbery in Augusta.
Prosecutors say McClain held Brown up at gunpoint, took $130 from the register and then shot and killed Brown as he left the store.
