Alabama Corrections officials are preparing for Thursday's scheduled execution for convicted cop killer George Sibley Junior.
The execution will take place at Holman Prison near Atmore.
Sibley, who is 62, was sentenced to die for the 1993 killing of Opelika police officer Roger Motley Junior in a shopping center parking lot.
His common-law wife, Lynda Lyon Block was executed in May 2002 after she and Sibley had for years failed to file appeals.
If the execution is carried out, Sibley will be the third Alabama man put to death this year.
