Witnesses described how Sanchez was abused at home and picked on at school. His sister said when she asked him why he doesn't show love, "He said he doesn't know what love is."
The defense argues Sanchez should get life in prison because of his age and background. The prosecution says the fact that Diener was shot during a robbery calls for the death penalty.
