A Zachary teenager died in a single-vehicle crash early Sunday morning in East Feliciana Parish, Louisiana State Police said.

Shortly after 1 a.m., 16-year-old Caleb Copeland was driving westbound on La. 959 east of La. 409 when he began passing another vehicle “at a high rate of speed as he entered a curve,” State Police said in a news release. Copeland failed to negotiate the curve and struck a guard rail on the east side of the road, causing the vehicle to become airborne and overturn.

Copeland was wearing a seat belt but sustained fatal injuries in the crash, State Police said. It is unknown if impairment was a factor in the crash, but a toxicology sample was taken from the teen for analysis.
