Georgia is poised to become the first state in the nation to execute an inmate since the U.S. Supreme Court decided in September to review Kentucky inmates' claims that lethal injection is unconstitutional. The court ruled last month that Kentucky's method of executing inmates, also used by about three dozen other states, is constitutional.

The last execution in the U.S. was Michael Richard of Texas on Sept. 25, 2007.

These are some of the executions that have been scheduled since the U.S. Supreme Court ruling last month:

GEORGIA: William Earl Lynd, 53, scheduled to die at 7 p.m. Tuesday. He was convicted of kidnapping and killing his live-in girlfriend, 26-year-old Ginger Moore, and shooting her three times in the face and head nearly 20 years ago.

MISSISSIPPI: Earl Wesley Berry, 49, on May 21, for the 1987 slaying of Mary Bounds. Berry was convicted of kidnapping Bounds from the parking lot of the First Baptist Church in Houston, Miss., and beating her to death.

OKLAHOMA: Terry Lyn Short, 47, on June 17, for throwing a homemade explosive into an Oklahoma City apartment building in 1995, resulting in the death of 22-year-old Ken Yamamoto.

TEXAS: Jose Medellin, 33, on Aug. 5, for his participation in the gang rape and strangulation deaths of two teenage girls 15 years ago in Houston.
