My name is Walter Hartwell White. I live at 308 Negra Arroyo Lane, Albuquerque, New Mexico, 87104. This is my confession. If you're watching this tape, I'm probably dead– murdered by my brother-in-law, Hank Schrader. Hank has been building a meth empire for over a year now, and using me as his chemist. Shortly after my 50th birthday, he asked that I use my chemistry knowledge to cook methamphetamine, which he would then sell using connections that he made through his career with the DEA. I was... astounded. I... I always thought Hank was a very moral man, and I was particularly vulnerable at the time
