Two north Mississippi men have died after they crashed into each other while riding all-terrain vehicles.

Local news outlets report the head-on crash happened Thursday evening near Byhalia.

Dead are 23-year-old Tevin Hardin and 29-year-old Denorris Robinson.

The Marshall County sheriff’s office says the men were not wearing helmets. Relatives say the two men are friends and neighbors who had long ridden ATVs together.

Both men died before they could be taken to a hospital. Relatives say no one witnessed the collision, making it hard to determine what happened.

Hardin’s uncle, Sammie Phillips, says another relative who was riding an ATV found the pair dead in the road. There’s no evidence any other vehicle was involved.
