FANNIN COUNTY, TX -- 13 years after a Texoma woman was murdered and her mutilated body was found discarded in the Red River her killer still hasn't been caught.

    

Now as her family struggles to find closure.. They're trying to get the investigation re-opened.

Jennifer Harris was 28 when she disappeared from Bonham on Mothers Day 2002.

After an exhaustive search her body turned up in the Red River found by a fisherman.

The Oklahoma City Medical Examiner’s office said all of her female organs were missing.  The autopsy showed they had been forcibly removed.

    

Jennifer's father, Jerry Harris, believes his daughter was pregnant at the time of her death and there's a good chance that's why she was killed.

"She thought she was pregnant.  Whether she was or not, we don't know," said Harris.

But the investigator Jim Holloway feels that if she was, the motive is very clear.

"The person that would have maybe got her pregnant certainly thought she was, because they went to great lengths to kill her," he said.

The Texas Rangers initially named Jennifer's ex-boyfriend, James Hamilton, as the prime suspect in the case.

    

But, the investigation stalled 2 years after her death when the sheriff's office announced that all of the evidence in the case had gone missing.

"Jennifers body was found in the Red River, it was transferred to the Oklahoma Medical Examiners Office. The evidence was lost once it was transferred from Oklahoma to Texas officials."

Current Sheriff Donnie Foster won't discuss the case on camera, but he told us that while he wasn't sheriff when it happened, he is protecting the evidence that still does exist.

Former Fannin County District Attorney Myles Porter says, the case cost him his office.

    

He told us by phone that rumors that he had been romantically involved with Jennifer Harris were totally false and that he had never even met Jennifer.

Jim Holloway is a free-lance investigator who volunteered to look into the case back in 2009.

    

He believes it can still be solved and that there's plenty of evidence investigators never bothered to look at.

"It was two years before the Texas rangers cold crime unit sent a ranger up here two years after the murder," said Holloway

Holloway says Jennifer's family deserves to know what happened and that's why he's joining their effort to get the sheriff to open up his files for the TNT TV show, "Cold Justice."

"I don't know why he would refuse to have some outside help, especially if it was professional, and that's their business, is solving cold case murders," Holloway said.    

    

Producers of the show say the sheriff has agreed to meet with them in the future but won't say when.

The sheriff says they have rescheduled several times and is not sure when the set date will be.

But even if the show does put a spotlight on the case Jennifer's family has no guarantee it'll ever be solved.

"12 years later, 13 years later, there's nothing here that can be used as evidence," said Harris.
