A Missouri man convicted in February of killing a Nebraska woman more than 20 years ago has lost his bid for a new trial.

Judge Karin Noakes ruled against the appeal filed by John Oldson. His filing said there was new evidence to consider.

A Howard County jury had found the 46-year-old Oldson, of Randolph, Mo., guilty of second-degree murder. He was charged with killing 31-year-old Catherine Beard, a waitress from Ord. She disappeared in 1989. Her remains were found outside Ord in 1992.

Oldson, who used to live in Ord, was interviewed in 1989 but not arrested. He was arrested a year ago in Missouri. Authorities say new evidence and witnesses led to his arrest.
