Steve Ennis is arrested in New York City after a sting operation catches him buying and selling ecstasy. His girlfriend, Jennifer Marcum, is with him at the time but not implicated in the drug ring.

Ennis would eventually be sent to the federal prison in Littleton, FCI-Englewood, where he ends up sharing a cell with Scott Kimball.

Having returned to Colorado from Dallas, LeAnn Emry files for a divorce from Kevin Niner.

She becomes romantically involved with Steven Holley, an FCI-Englewood prisoner whom she met through Niner.

Holley, facing a life sentence on charges that he shot at an officer during a Lakewood bank robbery, is held in the same prison unit as Scott Kimball.

Scott Kimball is transferred from the Alaska prison system to FCI-Englewood, a federal penitentiary in Littleton, Colo.

He had told federal authorities that seven Alaska inmates wanted to kill him for cooperating with the government.

The FBI activates Scott Kimball as a “cooperating witness” while he is an inmate at FCI-Englewood.

He tells an agent that his cellmate, Steve Ennis, asked him to kill a fellow drug dealer, and that Ennis’ girlfriend, Jennifer Marcum, would help.

After claiming that his cellmate, Steve Ennis, asked him to kill a fellow drug dealer, Scott Kimball is released from FCI-Englewood “to actively cooperate with the FBI on the Steven Ennis matter.”

Ennis, Kimball claims, told him his girlfriend — Jennifer Marcum — would help carry out the hit.

As a paid FBI informant, Kimball is given the name Joe Scott and told to keep an eye on Marcum.

His contact at the bureau is Special Agent Carle Schlaff.

After his release from FCI-Englewood as an FBI informant, Scott Kimball calls LeAnn Emry for the first time. He introduces himself as “Hannibal.”

Emry’s boyfriend, federal inmate Steven Holley, knew Kimball behind bars, and asked him to connect with LeAnn to share the details of a plan to help him escape prison.

Holley told LeAnn to listen to Hannibal, that if everything went off as it should, the couple would soon be able to unite in Mexico and start a new chapter in their lives.

LeAnn Emry’s boyfriend, FCI-Englewood inmate Steven Holley, writes a letter to her father, telling him he’s worried because he hasn’t heard from LeAnn in more than a month.

“So have you heard from her and is she alright?” he asks Howard Emry.

Frantic, Steven Holley writes another letter to Howard Emry from FCI-Englewood.

LeAnn is in “real trouble,” he warns.

“I don’t fully understand what the hell she thought she was doing, but I know she is way out of her league!”

Holley asks Howard Emry to call the FBI and have an agent come talk to him in prison.

Statement from Alderman to FBI Agent Jonathan Grusing, reprinted in a Lafayette police report.

Scott Kimball absconds with $7,300 and a pickup truck and trailer from his former FCI-Englewood cellmate John Alderman.

Alderman, a doctor convicted of tax evasion, said he had just been released from prison and needed help getting on his feet. He asked Kimball to pick up the truck and trailer, which he planned to live in, and to cash his $7,300 check since he had no bank account.

Alderman, 69, never saw Kimball again.

No charges were pressed.

Investigating Jennifer Marcum’s disappearance, FBI Special Agent Jonathan Grusing and Lafayette police detective Gary Thatcher interview Steve Ennis, who shared a cell with Scott Kimball at FCI-Englewood while dating Jennifer.

Ennis — being held at a federal prison in Seagoville, Texas — tells the investigators of another former FCI-Englewood inmate with an eerily similar story.

Steven Holley

Like Ennis, this inmate had become friends with Kimball behind bars in 2002. Like Ennis, he had put Kimball in touch with a girlfriend upon his release.

Both women went missing within weeks.

Talk to Steven Holley, Ennis told the investigators.

Holley, the inmate who had dated LeAnn Emry, had never had his own plea for an FBI interview granted.

FBI Special Agent Jonathan Grusing and Lafayette police detective Gary Thatcher interview Steven Holley at the federal prison in Florence, Colo.

They learn that his girlfriend, LeAnn Emry, had been with Scott Kimball in the month before she disappeared on Jan. 29, 2003.

Holley, who spent time in the same unit as Kimball at FCI-Englewood in 2002, said Kimball went by the name “Hannibal.”
