Boulder County prosecutors Amy Okubo and Katharina Booth, assigned to the Lafayette check-fraud case against Scott Kimball, meet with the U.S. Attorney’s Office and the FBI in Denver, asking for a wider investigation.

Lafayette police Detective Gary Thatcher had found out about Kaysi McLeod’s disappearance, and had also been told by FBI Special Agent Carle Schlaff that Kimball might be connected to the disappearance of Jennifer Marcum.

But neither federal agency launched a missing-persons probe.

Boulder County issues a warrant for Scott Kimball’s arrest on suspicion of theft, forgery and false reporting.

The charges stemmed from the theft of $55,000 from Lafayette optometrist Cleve Armstrong.

In the course of that investigation, police also found a trailer on Kimball’s former property that he had reported stolen two months earlier.

Kimball had already collected a $10,000 insurance claim for the trailer.

Boulder County prosecutors make a deal with Scott Kimball.

He pleads guilty to stealing $55,000 from Lafayette optometrist Cleve Armstrong as a habitual offender, and is sentenced to 48 years in prison.

In exchange, prosecutors draw up a memorandum of understanding in the missing-persons case. If he will lead investigators to the bodies of Jennifer Marcum, LeAnn Emry and Terry Kimball, he will only face a single count of second-degree murder.

They will otherwise pursue a first-degree murder conviction, punishable by life in prison without parole or the death penalty. But that will be difficult with only one set of remains — Kaysi McLeod’s — that show no evidence of the cause or manner of death.

For prosecutors Amy Okubo and Katharina Booth, the deal represents their only chance of finding the missing victims.

“Unfortunately, we couldn’t do that without his help,” Booth said. “It was a deal with the devil.”

Scott Kimball leads investigators and FBI agents on a hunt for bodies in eastern Utah, where he claims LeAnn Emry and Jennifer Marcum are buried.

During a second hunt for bodies, Scott Kimball leads investigators to a wash in Bryson Canyon.

FBI Special Agent Jonathan Grusing is the first to find a bone and then additional remains. They are later determined to be LeAnn Emry’s, based on DNA from her parents, Darlene and Howard Emry.

Boulder County prosecutor Katharina Booth said coming upon Emry’s bones was extremely emotional and moving.

A fragment of a brass-jacketed bullet is found the next day in the area where LeAnn’s skull would have been located when she was killed.

In a separate search for Jennifer Marcum’s remains, which Kimball insists are nearby, nothing is found.

Amy Okubo, also a chief deputy with the Boulder County District Attorney’s Office, said Kimball knows exactly where Marcum is and was simply “messing with us.”

Scott Kimball participates in a third search for bodies, insisting that Jennifer Marcum is buried in the same area of eastern Utah that LeAnn Emry’s remains had been found the previous month.

But no new discoveries are made, and Kimball tells the FBI that Jennifer may be buried as far as 60 miles away from the site being searched.

Jennifer’s body has still never been found.

Investigators suspect that Kimball may be hanging on to the information as leverage, as a way of extracting something of value from someone somewhere down the road.

“If he thought giving up Jennifer’s remains would benefit him, he would say where they are,” FBI Special Agent Jonathan Grusing said.

Kimball says the FBI won’t provide him the resources to find Jennifer.

“From day one I told the FBI that finding Jennifer would be the hardest to find,” he wrote in response to questions from the Camera. “I’m willing to keep looking.”

Without Jennifer Marcum’s body, Boulder County prosecutors revoke their deal with Kimball.

In a December 2008 “memorandum of understanding,” Kimball had agreed to lead investigators to the bodies of LeAnn Emry, Jennifer Marcum and Terry Kimball. In return, he would face only one count of second-degree murder.

In a letter to Kimball’s public defenders, Boulder County District Attorney Stan Garnett writes that Kimball is considered “in breach” of the deal.

Scott Kimball pleads guilty to two counts of second-degree murder in the deaths of LeAnn Emry, Jennifer Marcum, Kaysi McLeod and Terry Kimball, and is sentenced to 70 years in prison.

In an emotional hearing at the Boulder County Justice Center, the victims’ families finally have a chance to face the man who killed their loved ones.

LeAnn Emry’s mother said her daughter was “no more important to him than the carcass of a dead animal.”

“He made the deliberate choice to murder, and he made that choice at least four times,” Darlene Emry said through tears.
