OGALLALA, Neb. (AP) — A 22-year-old Kansas man has pleaded not guilty to vehicular homicide charges for the crash deaths of four Iowa residents in western Nebraska. The North Platte Telegraph reports that Jeser Cisneros-Hernandez, of Liberal, Kansas, entered the pleas Friday in Keith County District Court.

Cisneros-Hernandez is charged with four counts of motor-vehicle homicide, reckless driving and driving left of the center of the road. Prosecutors say hit two motorcycles carrying two people each on July 1 near Ogallala.

Authorities say 54-year-old Sheila Matheny and 61-year-old James Matheny, from Bedford, Iowa, were on one motorcycle. The other riders were 58-year-old Michal Weese and 59-year-old Jerolyn Weese, who lived in Council Bluffs, Iowa.

Cisneros-Hernandez’s next court appearance is scheduled for Dec. 8.
