INMATE INFORMATION
Last Statement:
I am the sinner of all sinners. I was responsible for the ’75 and ’79 cases. My trial was not just; it was not fair; they lied against me. I love all of those on Death Row, and I will always hold them in my hands. Those who stood by me, I will always love you. Jim and Judy Peterson and Chaplain Lopez, I thank you for staying by my side.

Last Statement:
First of all, I want to say God bless everyone here today. For many years I have done things my way, which caused a lot of pain to me, my family and many others. Today I have come to realize that for peace and happiness, one has to do things God’s way. I want to thank my family for their support. I love you. I am taking you with me. You all stay strong. I love you. I also want to say thanks to the Chaplains who I have met through the years and who have brought me a long way. And I cherish you as my family and at this time…oh, Ken, my little son, I am coming to see you. Oh Lord, into your hands I commit my spirit. Thy will be done.
