This week in Alabama an 83 year old man, Walter Moody, who had spent 22 years on death row, was executed by lethal injection, for sending a lethal mail bomb to a judge back in 1989.

Definitely a record for the USA. Pretty certainly a world record too. Not for the length of time on death row before being executed - that stands at at least 33 years. But there are a few who've been on death row longer than that, so that might well be broken. The same could apply to oldest - the oldest man on death row was 94, but then he went and died without needing any lethal injections...
