Investigators in northeastern Kansas say a motorist who struck and killed a 21-year-old college student might not have realized that someone had been hit.

KMAN-AM reports the victim has been identified as Manhattan resident Konley Harding, a student at Manhattan Area Technical College.

The Pottawatomie County sheriff’s office says witnesses saw a small SUV crossover or large sedan run over the victim around midnight Saturday on U.S. 24, about two miles east of Manhattan.

The vehicle continued without stopping. Authorities say Harding was wearing dark clothing and, according to witnesses, had been lying in the roadway. The sheriff says the driver was probably aware of hitting something, but not necessarily that it was a person.

Investigators are reviewing tapes of traffic in the area at the time.
