DENVER , Colorado -LRB- CNN -RRB- -- Serving time for lesser crimes , Scott Kimball is leading investigators to bodies . Scott Kimball is currently serving a 48-year sentence on theft and habitual criminal convictions . Partly mummified bones thought to be those of his uncle , Terry Kimball , were discovered Monday in a remote Rocky Mountain pass near Vail , Colorado . DNA tests are pending to confirm the victim 's identity , and the cause of death is pending a forensic examination , authorities said . Terry Kimball is one of several suspected homicide victims associated with Scott Kimball since his jailing in 2008 . He is serving a 48-year sentence in state prison in Fairplay , Colorado , on theft and habitual criminal convictions . Kimball will also serve a 70-month federal sentence on firearms charges after the state sentence . The firearms charges led to Kimball 's 18th conviction . However , Kimball probably will 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 . Earlier this year , Kimball revealed where the remains thought to be his uncle 's were , according to law enforcement sources close to the case . However , the search was delayed until snow had melted . The FBI would not confirm that Kimball , 42 , identified the site . However , FBI spokeswoman Kathleen Wright said , `` we went to -LRB- a -RRB- specific location for a specific reason . It was n't random . '' Terry Kimball , 60 at the time , was last seen with Scott Kimball in September 2004 , according to a 2007 federal search warrant affidavit . Scott Kimball told his wife that his uncle had won the lottery and left for Mexico with a stripper , the affidavit said , but FBI investigators think Kimball killed his uncle and dumped his body in Vail Pass , more than 100 miles from the home they shared in a Denver suburb . 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 . Kaysi McLeod was 19 when she disappeared in 2003 . McLeod , the daughter of Kimball 's ex-wife , was last seen getting a ride to work from Kimball , according to the 2007 affidavit . In fall 2007 , a hunter found her remains in northwest Colorado . 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 . `` We are continuing to look for Jennifer , and we will leave no stone unturned , '' Wright said . Kimball drew the FBI 's attention in 2002 while jailed for writing bad checks . Kimball offered authorities information about his cellmate , Steven Ennis , who was suspected in a drug ring , according to the 2007 affidavit . After Kimball served his sentence , the FBI began paying him as an informant . Kimball was supposed to report back to the FBI on Marcum , Ennis ' former girlfriend , when she disappeared . The FBI would not reveal how long or how much Kimball was paid . He was arrested again in March 2006 near Palm Springs , California , after a police chase and standoff .
