One man died and another was seriously injured early Sunday morning when they got into an ATV accident while off-roading in Millstone Township, New Jersey State Police said.

Drew Bloodworth, of Montvale, and Dylan Kells, of Tom's River, were riding a John Deere Gator Utility Vehicle around 2 a.m. near Millstone Road when they crashed and were thrown from the ATV.

Bloodworth, 22, was pronounced dead at the scene from his injuries.

Kells, 21, was rushed to Capital Health Regional Medical Center in Trenton and is being treated for "serious injuries," State Police Sgt. Jeff Flynn said Sunday.

The incident is still under investigation, and police are not yet sure who was driving the ATV or what caused the crash, Flynn said.
