Using pilfered personal financial information from family friend and Lafayette optometrist Cleve Armstrong, Scott Kimball begins moving thousands of dollars over the phone from Armstrong’s money market account to Armstrong’s checking account.

Over the next three weeks, he transfers $83,000 between accounts, then uses several accomplices to forge nearly $55,000 worth of checks to Kimball’s companies: Rocky Mountain All Natural Beef and Rocky Mountain Cattle Company.

When Armstrong returns from vacation in mid-January, he will immediately point police in the direction of Kimball, who had an office in the basement of the 801 S. Public Road building shared by Armstrong and Kimball’s mother.

Once Lafayette optometrist Cleve Armstrong calls police about his missing money, Scott Kimball leaves the state.

He ends up in California’s Coachella Valley, where he stays in a rented casita with Denise Pierce, his 31-year-old girlfriend.

In investigating Scott Kimball for stealing $55,000 from optometrist Cleve Armstrong, Lafayette police Detective Gary Thatcher interviews Kimball’s now-estranged wife, Lori McLeod, and learns that her daughter has been missing for more than two years.

Lori McLeod says she has long suspected that her husband played a role in Kaysi’s disappearance.

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.”
