Jennifer Marcum is born in Aurora, Colo., to Bob Marcum and Mary Willis.

Her parents will divorce when Jennifer is 6 months old,  and she will move to Springfield, Ill., with her mother and older sister at age 4.

Jennifer’s interests ranged from Wiffle ball and volleyball to reading and studying wildlife — especially lizards. As she got older, she also developed an appetite for mischief.

“She was a wild cat,” Willis said. “Sneaking out and being defiant. Testing the boundaries.”

Because of trouble at home, Jennifer and her sister ended up in foster homes for a couple of years, but neither of her parents would share details.

“My ex-wife and I had a very dysfunctional relationship, and the kids didn’t enjoy life because of it,” said Bob Marcum.

Jennifer ended up dropping out of high school, marrying a former classmate and moving to Colorado Springs, where she got divorced after a year.

Jennifer Marcum starts stripping at Shotgun Willie’s, in Glendale, Colo.

A FoxNews television crew captures her first night, documenting her motivation and nervousness before taking the stage.

“I probably will cry, to be honest,” she says. “It’s a very scary feeling for me. I’ve always had manager jobs and (been) looked at as a very respectable person.”

She hopes the job will provide her the financial security to pursue bigger dreams with the father of her son, introduced on TV as her husband although the two never legally married.

“I could probably make more in a week than he can in two, and I’d like to live in a house, and so I have higher goals,” she tells the TV crew.

Jennifer’s father, Bob Marcum, said his daughter worked as a stripper primarily to support her son. She kept the job until her death, but Mary Willis, Jennifer’s mother, said she was anxious to get out at the end.

“She was wanting away from there real bad,” Willis said.

Hoping that his missing daughter might be in jail somewhere, Bob Marcum asks a cop friend to run Jennifer Marcum’s name through a national criminal database.

The next day, he gets a call from FBI Special Agent Carle Schlaff, who’d been alerted of the database search.

Scott Kimball had passed a lie-detector test after telling his FBI handler that a drug-dealer killed Jennifer. And when asked why he had Jennifer’s furniture, Kimball had given the agent a lease showing that he paid $400 to rent it for a year.

But Schlaff doesn’t share those details with Bob Marcum. He says there are few leads in the case, and that Jennifer “just dropped off the map” after leasing her furniture to a man.

After trying for more than a year to find the man with their daughter’s belongings, Bob Marcum and Mary Willis fly to Denver and put up fliers of Jennifer Marcum all over town.

Bob Marcum talks again with FBI Special Agent Carle Schlaff, pushing for information about the man with Jennifer’s furniture.

Schlaff won’t give up the man’s name, but eventually gives Marcum a cell-phone number for Scott Kimball.

Ask for Joe Snitch, the agent says.

Hoping to find out more from the man who has their daughter’s furniture, Jennifer Marcum’s parents meet with Scott Kimball, whom they know only as ‘Joe Snitch,’ at Broomfield’s North Midway Park.

Joe Snitch tells Bob Marcum and Mary Willis that Jennifer had been murdered, and he knows who did it and where they left her body. He tells Willis that if she’ll let him into her hotel room that night, he can demonstrate how Jennifer was killed.

In a second face-to-face meeting, Scott Kimball returns Jennifer Marcum’s furniture and belongings to her parents, Bob Marcum and Mary Willis.

Kimball, who’s had Jennifer’s items since she disappeared in February 2003, is accompanied by FBI Special Agent Carle Schlaff.

They all convene in a strip mall parking lot in Broomfield for the exchange.

Jennifer Marcum’s parents unveil a billboard outside of Shotgun Willie’s, the Glendale strip club where their missing daughter worked.

The billboard attracts media coverage, and in an interview with Denver’s Westword newspaper, Bob Marcum intentionally mentions Scott Kimball as an acquaintance of Jennifer’s.

Marcum had learned Kimball’s real name shortly after his surreal meeting with “Joe Snitch.”

Reading a Westword article about a billboard erected for Jennifer Marcum, Rob McLeod spots Scott Kimball’s name.

McLeod’s ex-wife is still married to Kimball, who lived with their 19-year-old daughter, Kaysi McLeod, when she went missing three years earlier.

McLeod calls Jennifer’s father, Bob Marcum, who mentioned Kimball’s name to the Westword reporter as an acquaintance she stayed with before vanishing.

“Now we’ve got two people missing, and there’s only one commonality — Scott Kimball,” McLeod said.

Bob Marcum, who has flown out to Colorado, meets with Rob and Lori McLeod to search for clues to their daughters’ whereabouts.

They drive to Scott Kimball’s former condo in Lakewood, where Jennifer had left her furniture, and talk to the manager there.

They scope out his former Adams County property, and a nearby field where Kimball had run cattle. A pit on the property contains the bones of slaughtered cows.

Convinced that Kimball has claimed more victims, Marcum asks the others: “Is there anyone else Scott Kimball has been around who you’ve never seen again?”

In fact, Lori McLeod responds, Scott’s uncle Terry had vanished a couple of years ago after living with them for several weeks.

“She said it like she had never thought about it before,” Marcum said.

Bob Marcum and Rob McLeod meet with Lafayette police Detective Gary Thatcher, who is investigating Kimball for check fraud, about their missing daughters.

They ask to have a bone pit on Kimball’s cattle pasture searched for human remains, but police find nothing.

The two fathers also meet with the FBI at the bureau’s Denver office and explain the similarities in their daughters’ cases. They tell the FBI about Terry Kimball, too, saying they don’t buy that he ran off to Mexico.

“You can look into this and see if it goes anywhere, or you can choose not to,” McLeod tells the bureau. “It’s your choice.”

After Bob Marcum and Rob McLeod meet with the FBI about their missing daughters, Special Agent Jonathan Grusing is assigned to investigate the missing-persons cases surrounding Scott Kimball.

Working with Lafayette police detective Gary Thatcher, Grusing launches an exhaustive investigation, looking for clues that Kimball had transitioned from a white-collar criminal to a serial killer.

Kaysi McLeod is laid to rest in Wheat Ridge, 6 1/2 years after Scott Kimball murdered her, and a few weeks after the FBI returned her remains to her family.

About 200 friends and well-wishers — including Howard Emry and Bob Marcum, whose daughters Kimball also killed — attend a memorial service at Bethlehem Lutheran Church. Kaysi’s divorced parents, Lori and Rob McLeod, walk down the aisle together as their 19-year-old daughter’s flower-draped casket is wheeled toward the altar.

“Life was not always easy, but her glass was always half full,” says Mike Harmon, a Baptist pastor and Lori McLeod’s half-brother. “She knew the Lord. She’s with him today.”

Then, the congregation gathers graveside in Crown Hill Cemetery as Kaysi is placed in the ground.
