A Lone Ranger
Apparently, he had a standard operating procedure, which he would follow when he would rob banks. He was always alone, he would often strike on Friday afternoons right before the bank would close, and had a large amount of cash on hand. He would wear one of his masks, wield a gun and wear big clothes, so no one could really tell how big or small he was, what color his skin was, and most importantly, what he looked like.
