More than 20 years after he committed the crime, Earl Wesley Berry was executed Wednesday evening by lethal injection at Missisippi's Parchman state prison. Berrys lawyer claims he is mentally retarded and shouldn't have been executed. They also claim Mississippis form of lethal injection is cruel and unusual punishment. He had been convicted and sentenced to death for the 1987 kidnapping and beating death of Mary Bounds. She was leaving church choir practice when she was abducted in Houston, Mississippi.
