A California man has been found guilty of murdering a baby girl by stepping on her and prosecutors revealed Friday that he told them he felt a sense of relief after committing the atrocious crime. Daniel Ruiz of Hesperia killed one-year-old Scarlett by placing his foot on her chest and crushing her with the force of most of his 230-pound bulk while the baby's mother was out buying milk. After crushing the baby, the San Bernadino County District Attorney said Ruiz flipped through channels on the television while Scarlett struggled desperately to breathe.
