Troy Davis wants polygraph ahead of execution
ATLANTA | Wed Sep 21, 2011 8:59am EDT
(Reuters) – A condemned man set to be executed by lethal injection on Wednesday for killing a Georgia police officer in a high-profile case wants a polygraph test in a last-ditch bid to show his innocence, Amnesty International USA said.
Troy Davis’ case has attracted international attention and an online protest that has accumulated nearly one million signatures because of doubts expressed in some quarters over whether he killed police officer Mark MacPhail in 1989.
Davis’ best hope of avoiding execution, set for 7 p.m. local time on Wednesday, lay with the Georgia Board of Pardons and Paroles but on Tuesday it denied him clemency following a one-day hearing.
