The Suffolk County District Attorney's office says Kim Jeonghyun, 25, smashed into a Colorado college student who had just gotten out of a taxi at Packard's Corner Saturday morning.

The victim sustained serious injuries, but is expected to survive. Jeonghyun is charged with drunk driving, negligent operation of a motor vehicle and leaving the scene of an accident.
