PAUPACK, Pa.—A New Jersey man faces vehicular homicide charges in the death of a vacationing college student fatally struck this summer in northeastern Pennsylvania.

Pike County prosecutors say 48-year-old Philip Cise of Dover, N.J., didn't have a prescription for two painkillers he took shortly before the July 14 crash that killed 20-year-old Gabrielle Reuveni.

Investigators say a witness saw Cise swerve and hit the Paramus, N.J. woman while she went jogging during a family vacation in Palmyra Township.

Cise is being held in New Jersey on charges related to a crash there a day later. It's not clear if he has an attorney.

Cise had been arrested earlier in July after police said he threatened a person with an ax.

Reuveni was a junior at Washington University in St. Louis.
