A Yale medical school student near the end of her studies died Sunday morning of injuries she suffered when she was struck by a car while crossing the street Saturday. The medical student was supposed to graduate in May and begin her residency this fall at the Highland General Hospital Department of Emergency Medicine, part of the Alameda County Medical Center in Oakland, Calif. The student was crossing South Frontage Road at York Street near the Yale School of Medicine when she was hit about 9:45 a.m., according to a spokeswoman for the mayor’s office. She suffered serious head trauma. It is unknown at this time if the police found the driver of the car that struck the student at fault.
