To Gwinnett County District Attorney Daniel J. Porter, the questions two Georgia Supreme Court justices tossed at his assistant during recent oral arguments “sort of caught us flat-barted.”

The big draw on the court’s Feb. 29 docket was one of Porter’s most high-profile cases: the appeal of Kelly Gissendaner, the mother of three young children who was convicted of murder and sentenced to death for inducing her lover to kill her husband. Her lover, Gregory Owen, pleaded guilty, testified against Gissendaner and received a sentence of life with no parole for 25 years.
