On 7 June 1999, Valle, then 23, and four other men went to the Pasadena home of Jose Junco, a known drug dealer. Assuming they wanted to buy drugs, Junco went outside to meet them. They then produced guns and ordered Junco to return inside, with his hands in the air. Junco told his girlfriend, Amy Lindgren, not to look at the men, and he covered her face with a pillow. Next, the men argued with Junco about drugs and money. Eight or nine shots were fired. Lindgren stayed on the floor until the men drove away. She then got up, saw Junco's dead body, and called 9-1-1. The assailants stole two rifles and a cookie tin containing money, drugs, and sexually explicit photographs.
His final statement before death: "I am sorry, I never wanted to kill your family. I never wanted to kill your family or these people. I am sorry for the way I talk in English. I did it to myself. I was forced to do it. I was a gang member. I never wanted to kill your brother. I was forced to do this. I blame myself. I am not going to blame nobody. I got my mother and my family too. I was forced. I tell you from my heart. I am sorry with all my heart. That's the reality of life, I am sorry. I got to pay for it. To my family, I love you, be strong. They have family too; the way they suffer is the way I am suffering. I am asking you to go and give them hugs. Please accept their hugs. Be strong in the Lord. I love you sister. I love you all, please go and try and talk to the family. I love my family. I understand why I am paying this price. Do not have any excuses for not extending your love. I am ready Warden, I am sorry everybody, I did it. Thank you brother, don't hate nobody, I feel good. I love my family, I love you Jesus. Be strong mama, I love you sister. I love Jesus. Warden I am ready."
