OGALLALA, Neb. (AP) — The Nebraska trial of a Kansas man charged with the traffic deaths of four Iowa motorcyclists has been delayed until August. Keith County District Court records say the trial was scheduled to begin Tuesday for 23-year-old Jeser Cisneros-Hernandez, of Liberal, Kansas. He’s pleaded not guilty to four counts of vehicular homicide, one of reckless driving and one of failing to drive in his lane.

The records say the judge last week granted the delay because the attorneys have not completed the pretrial discovery process. The new starting date is Aug. 6. Prosecutors say Cisneros-Hernandez’s vehicle hit two motorcycles carrying two people each on July 1, 2017, near Ogallala. Authorities say 54-year-old Sheila Matheny and 61-year-old James Matheny, from Bedford, Iowa, were on one motorcycle. The other motorcyclists were 58-year-old Michal Weese and 59-year-old Jerolyn Weese, who lived in Council Bluffs, Iowa.
