Kiplyn's parents may testify

The parents of 15-year-old Kiplyn Davis may be taking the witness stand to testify against the man convicted of lying to authorities about his role in the teen's disappearance 10 years ago and now facing trial in her murder.

In a motion filed by federal prosecutors asking a federal judge to increase the sentence for Timmy Brent Olsen, prosecutors say they may call Tamara and Richard Davis to testify about the emotional trauma they have suffered for the past 10 years and more recently when Olsen reportedly led federal agents on a "wild goose chase" to show them where Kiplyn's body was and then changed his story, saying he made the tale up.

"Of all human traumas, few compare to the loss of a child under circumstances that strongly suggest violence both sexual and physical," wrote assistant U.S. Attorneys Richard Lambert and Carlos Esqueda. "Compounding the horror is the uncertainty of the actual circumstances of Kiplyn's death and the location of her body. Without the resolution of these uncertainties, including justice for the perpetrators, closure is nigh unto impossible for the family and the community."

Prosecutors say they plan to have Kiplyn's parents tell of the "emotional and psychological" pain of hearing reports that Olsen had in the past admitted to killing their daughter only to have him now "doing all he could to prevent law enforcement and the family from ascertaining the true facts."

According to transcripts of taped phone conversations and copies of letters, prosecutors point to indications that Olsen, even after being found guilty by a jury last July of lying about his role in Kiplyn's disappearance, told his girlfriend and family to keep quiet about things that he told them.

In grand jury testimony, Olsen's girlfriend, Kristina Gordon, testified that during a jail visit with Olsen on July 21, two days after his conviction, Olsen communicated to her by "mouthing" words and making gestures that he and co-defendant David Rucker Leifson had taken Davis up Spanish Fork Canyon on the day she disappeared. Gordon then testified that Olsen communicated to her that he blamed Leifson for killing Davis. At the time, Olsen said he couldn't tell her everything because they were being listened to by jail staff.

On several occasions, Olsen has complained about being recorded while talking to family and friends from jail.

Prosecutors claim this is evidence that Olsen continues to hide the truth and is asking a federal judge to find that Olsen has obstructed justice and give him more than 30 years in prison when sentenced on Nov. 21.
