 I'm Lisa Taylor. The Uvalde police officer who was in charge when 19 students and two teachers were murdered in a school shooting is pleading not guilty to child endangerment charges. Peter Arredondo was the former Uvalde school district police chief. He's already been fired. He was arrested but has since posted a $10,000 bond and been released. There's another court hearing set for next week. The Mediterranean diet could improve a child's heart health. Michael Kastner reports.
