Carey Dale Grayson, 50, fought his restraints and raised both middle fingers just before gas was administered, a witness said.

An Alabama prisoner convicted of the 1994 murder of a female hitchhiker became the third person executed by nitrogen gas in both the U.S. and Alabama.

Grayson was convicted with three other men for the brutal slaying and mutilation of 37-year-old Vicki Lynn Deblieux.
