The last of five men suspected of lying in connection with the disappearance of Spanish Fork High School student Kiplyn Davis pleaded guilty in federal court today to lying to a federal grand jury when asked if he had two heated arguments with a second man, now charged with Davis' murder.

David Rucker Leifson appeared in U.S. District Court with his attorney to enter a plea of guilty to one count of perjury as part of a plea bargain reached with federal prosecutors one week before he was scheduled to stand trial on the charges.

In court, Leifson admitted he lied to the grand jury when questioned about the disappearance of 15-year-old Davis, who vanished from Spanish Fork High School on May 2, 1995.

Specifically, Leifson admitted to lying about having two heated arguments with suspect Timmy Brent Olsen, furious that Olsen had told others that Leifson was behind Davis' disappearance. According to the indictment against Leifson, two people were witness to both confrontations and a third witness, while wearing a concealed wire, recorded Leifson admitting to having the arguments.

When sentenced on Jan. 10, Leifson faces up to five years in federal prison.

Leifson is the last out of five suspects who have either accepted plea deals or who have been found guilty by a jury of lying to the grand jury and investigators.

Two other men, Scott Brunson and Garry Von Blackmore pleaded guilty and have agreed to testify during two upcoming murder trials. Olsen was found guilty of perjury by a jury and sentenced to 12 years in federal prison last year. He now stands charged with murder.

Last September, a federal jury also found Christopher Neal Jeppson guilty of perjury. Jeppson is scheduled to be sentenced on the perjury counts on Jan. 9. On Oct. 11, Jeppson became the second man to be charged in state court in Davis' murder.

U.S. Attorney for Utah Brett Tolman issued yet another plea for people to come forward with information, adding "time is running out" for some to come forward with information. Although five men have been found guilty of lying in the Davis case, no one has yet to come forward with solid information about where Davis may be buried or what exactly happened to her.
