As a person
with technical skills, Alfred was a customer at many Radio Shack Stores
in Massachusetts. Click here for copies
of 97 saved receipts from 12 stores, including two receipts
from the Radio Shack store at 197 Mass. Ave. The first of those two was
on 4 May 1990, before the Roslindale Bomb explosion, and the second on
1 May 1992, before Alfred knew that a receipt for "SAHY JYT"
from that store would become an important part of the trial.
