McALESTER, Okla. (AP) — An Oklahoma man who was put to death Tuesday evening despite claims that he was insane spent his final moments rambling about the presidential election and appeared startled when a prison official announced the start of the execution.

Garry Thomas Allen, 56, was executed for the 1986 killing of his fiancee, 24-year-old Lawanna Gail Titsworth, outside an Oklahoma City day care. His attorneys had argued that Allen shouldn’t be put to death because he couldn’t understand the judgment against him.
