PROVO (AP) — A man charged with the murder of 15-year-old Kiplyn Davis will request a new trial in his federal perjury case.

Christopher Neal Jeppson was convicted in September of one count of perjury and three counts of making false statements.

The charges stemmed from statements Jeppson made to a federal grand jury investigating Davis's disappearance from Spanish Fork High School in 1995. Her body has not been found.

Jeppson's attorney, Scott Williams, says he wants to file a motion requesting a new trial in the next several weeks.

Williams says the motion is based on evidence he obtained in Jeppson's murder case that wasn't available to him during the perjury case.

Williams would not say what evidence was not made available to him during the federal perjury trial.

Jeppson, along with co-defendant Timmy Brent Olsen, is charged with Davis's murder in Provo's 4th District Court. Several witnesses from the perjury trial testified at Jeppson's preliminary hearing on the murder charge in January, including his ex-wife, ex-girlfriend and law enforcement agents from the FBI and Spanish Fork police who interviewed Jeppson about Davis's disappearance.
