4 Central Coast volunteers were killed in a plane crash in Mexico last week. The volunteers with “Flying Samaritans”, were on a mission from San Luis Obispo to provide medical care to families in need in Baja California. The volunteers died Friday after their plane crashed about 30-miles outside Ensendada. On board the fatal crash was Doctor Graciela Sarmiento of Arroyo Grande, plastic surgeon, Doctor James Thornton, medic and Cal-Poly graduate Andrew Thiel, and pilot Roger Lyon of Cayucos. Funeral services are currently being planned by family members.
