PROVO - Scott Brunson fulfilled part of the requirements of his plea bargain by testifying against a high school classmate Tuesday.

Brunson, who pleaded guilty to two counts of lying to federal investigators and a charge of perjury, testified in 4th District Court that Timmy Brent Olsen asked him to tell police that Olsen was at Brunson's house the day Kiplyn Davis disappeared. Brunson said he initially refused, and even pointed out one lie Olsen told investigators about seeing a man and woman in a car in Spanish Fork Canyon.

"I said I wasn't going to lie for him," Brunson said. But when Olsen repeatedly told Brunson he had nothing to do with Kiplyn's disappearance and investigators refused to believe him, he agreed to provide an alibi.

Brunson was one of several witnesses prosecutors called in on the second day of a preliminary hearing for Olsen and Christopher Neal Jeppson, who have been charged with Kiplyn's murder.

Brunson testified that Olsen also made what he thought were some strange statements in the days and weeks after Kiplyn's May 2, 1995, disappearance from Spanish Fork High School. In one instance, Olsen said he didn't want to go to prison.

In cross examination, defense attorney Dana Facemyer had Brunson admit that a head injury when he was a teenager has given him some memory problems. Brunson also said, in response to attorney Scott N. Williams' questions, that he had no knowledge Jeppson was involved in Kiplyn's disappearance.

But Karen Knudsen, who dated Jeppson in 2001, said Jeppson had told her he killed Kiplyn and helped dispose of the body. She said Jeppson made the admission while they were playing a game where they revealed personal secrets about each other.

"He said, 'I killed Kiplyn Davis. I'm just joking. I helped get rid of her body. I'm just joking,' '' Knudsen said, noting Jeppson's demeanor was perfectly calm.

But Williams said the only mention of the incident in Knudsen's diary was a postscript on one entry that said "Dead girl joke: Not funny." The same journal also had a 6 1/2 -page entry on how Jeppson tore up pictures of him and Knudsen.

Although Kiplyn's body has not been found, officials believe she was murdered. The investigation in the case stalled but was revived in 2003 and five men - Olsen, Jeppson, Gary Von Blackmore, Brunson and David Rucker Leifson - were charged with perjury and lying to federal investigators. Olsen and Jeppson were convicted of lying, while the others pleaded guilty.
