David Gutierrez, 15, was stabbed in the heart on Valentine’s Day at Santana Row mall in San Jose, California. The murder trial of a boy, who was 13 years old when he was arrested and charged with murder, began with an emotional opening statement from his mother, Veronica Gutierrez. The case has raised questions about juvenile justice and led to protests from David's family and youth advocates. If convicted, the minor could face 8 months in a youth ranch program, which critics argue is too lenient. The defense attorney suggested that the suspect had no intent to kill David, but his girlfriend may have egged on the confrontation. Police and David's parents claim that David had no gang ties and was wearing the jacket to celebrate Valentine's Day.
