School, police and state CPS officials all received warnings that teen was unsafe. There were no police on the case. No news reporters shoving cameras in family members’ faces. No detectives scavenging for clues. There was only Amythist McCart, a 17-year-old high school senior, riding shotgun in her grandma’s white 2004 Oldsmobile, her grandma at the wheel and her cousin in the back seat.
