His last words before being executed were:

“Yes sir. I want to ask if it is in your heart to forgive me. You don’t have to. I know I allowed the devil to rule my life. I just ask you to forgive me and ask the Lord to forgive me for allowing the devil to deceive me.
I thank God for having patience with me. I don’t deserve to cause you pain. You did not deserve this. I deserve what I am getting.”
