Investigators are working in concert with killer Scott Kimball:

Scott Kimball is serving a 48 year prison term at state prison Fairplay, Colorado.

However, Kimball is leading investigators to multiple bodies and solving many crimes. The mummified remains of who is thought to be Terry Kimball (Scott’s Uncle), were discovered on Monday.

Once Scott Kimball finishes with his state sentence, he will also have to serve a 70- month federal sentence of firearms charges.

The firearms charge was Kimball’s 18th conviction.

What is ironic is that Scott Kimball will probably not be charged in any of the deaths.

Sources with knowledge of the cases said Kimball’s December 2008 plea to theft and habitual criminal charges, and the 48-year sentence, was part of a deal that included revealing the locations of the bodies. Authorities wanted to give victims’ families resolution. Without his cooperation, authorities doubt they have enough evidence to convict him.

In March, Kimball accompanied FBI investigators to southeastern Utah to search for the body of Leann Emry, who was 24 when she vanished after departing on a camping trip in 2003. FBI agents found Emry’s remains shortly after Kimball returned to jail.

Kimball is also suspected in the disappearance of exotic dancer Jennifer Marcum, who disappeared in 2003, according to the affidavit.

Sources close to the investigation say they think Kimball killed Marcum and buried her body near Rifle, Colorado. Authorities have not found her remains.
