Richard Gerald Jordan, a 79-year-old veteran, was sentenced to death in 1976 for killing a bank loan officer’s wife

The longest-serving person on Mississippi’s death row was executed Wednesday, nearly five decades after he kidnapped and killed a bank loan officer’s wife in a violent ransom scheme.

Richard Gerald Jordan, a 79-year-old Vietnam veteran with post-traumatic stress disorder whose final appeals were denied without comment by the US supreme court, was sentenced to death in 1976 for killing and kidnapping Edwina Marter. He died by lethal injection at the Mississippi state penitentiary in Parchman.

The execution began at 6pm, according to prison officials. Jordan lay on the gurney with his mouth slightly ajar and took several deep breaths before becoming still. The time of death was given as 6:16pm.

Jordan was one of several on the state’s death row who sued the state over its three-drug execution protocol, claiming it is inhumane.
