Thomas Tilton Stone, a Vallejo resident, was a business major at Cal Poly.
Authorities say a 22-year-old college student struck and killed by a train may have been wearing earbuds and looking down at his phone when he walked onto the tracks on California's Central Coast.
Police say Thomas Tilton Stone was found unresponsive after being hit Tuesday in San Luis Obispo, where he attended California Polytechnic State University. He was pronounced dead at a hospital.
Witnesses tell investigators that Stone was checking his phone and did not respond to crossing arms or the train's horn prior to the collision. Police and coroner's officials continue to investigate.
