PIERCE, Neb. (AP) — A 21-year-old South Dakota man has pleaded not guilty to misdemeanor vehicular homicide in the crash deaths of three other people in northeast Nebraska.

Online court records say the attorney for Carlos Sanchez Espinoza entered the pleas on Wednesday in Pierce County Court.

The April 28 crash on U.S. Highway 81 in Pierce County killed 41-year-old Pablo Chilel Escobar, 29-year-old Mario Adan DeJesus Pinedo and 24-year-old Hugo Iglecias Moreno. Those men and six others in the vehicle were ejected from the SUV when it left the highway and rolled.

Authorities say it appears a tire blew out, causing the driver to lose control. The men were on their way to a construction site when the crash occurred.
