Joe Mitchell of Oklahoma City had just a few incidental questions for his wife, Eula Leigh Mitchell, to complete his application for Social Security retirement benefits. But he never made it to the reception area of the Social Security offices in the Alfred P. Murrah Federal Building to ask her. The explosion separated them. Leigh Mitchell, 64, an employee of Manhattan Cleaners and a Sunday school teacher in her church, loved animals and especially the birds around her home. Her family described her as a friend to many, particularly the elderly friends that she loved to take care of and shop for. Her husband of 26 years was injured in the blast.
