The state of Georgia had scheduled Kelly Renee Gissendaner's execution for 7 p.m. on Monday night, but postponed it "out of an abundance of caution," after questions arose about the lethal-injection drug to be administered, according to Georgia Department of Corrections spokeswoman Gwendolyn Hogan. Gissendaner, 46, was convicted of planning the 1997 murder of her husband by her boyfriend, Gregory Owen, who testified against her in a plea deal. This was the second delay in Gissendaner's planned execution, and Georgia officials didn't disclose a new date.
