The psychic sisters who assisted in the murder case of Christine Sheddy will appear on Investigation Discovery show "Six Degrees of Murder."

Included in the list of guests discussing Sheddy's death are the Pennsylvania-based, self-proclaimed "Psychic Sisters" Suzanne and Jean Vincent. The sisters claimed to have assisted the police in the 

investigation by means of psychic intuition and premonition.

"When I do this, I volunteer, which means I don't charge anyone, family or police, for my time," Suzanne Vincent said. 

Vincent stated that Sheddy's mother, Lynn Dodenhoff, had reached out to her after several family members had heard about her assistance in the 2006 murder of Blainesville, Pennsylvania dentist John Yelenic.

"When she had reached out to me, I knew she was gone," Vincent said. "But I also kept getting of two names; "Tia" and a second with a 'J,' Junior or Justin." 

In late-2007, Sheddy, then 26, was living with three other people in a farmhouse in Pocomoke City; Justin Hadel, then 17, Tia Lynn Johnson, then 26, and Clarence Butch Jackson, then 33. 

Johnson and Jackson were in a relationship together. However, Jackson was also engaged in a sexual relationship with Sheddy. When Jackson refused to take the relationship any further, Sheddy allegedly threatened to tell Johnson. At this point, Jackson told Hadel to "finish her off."

Hadel struck Sheddy three times with a two-by-four board and ultimately breaking every bone in her face below her forehead. Hadel and Jackson buried Sheddy's body in a shallow grave in the woods near the farmhouse.

Johnson, Jackson and Hadel later moved Sheddy's body to Snow Hill, burying her between the fence-line and a guest house at the River House Inn, where Jackson and Johnson had formerly worked. 

"When I tried to get an image of Sheddy's body, I kept seeing an image of bungalows, and I knew her body was buried somewhere by them," Vincent said.

Hadel would later move to Texas, and Jackson and Johnson to Tennessee. 

"I kept feeling a connection to Texas, that someone involved in the case had a relationship to Texas," Vincent said. "Police told me that there was a suspect who did have a Texas connection."

When Jackson was arrested in 2010 in connection with an arson in Hamilton County, Tennessee, he reached out to Dodenhoff, offering to give up information on where Sheddy was buried in order to get out of jail. Johnson and Jackson would later be tried, in 2012, for after-the-fact involvement in Sheddy's murder. Jackson would accept a plea deal for a 30-year sentence, stating that he was the ringleader of the murder.

Vincent also claimed that police had initially chalked up Sheddy's disappearance as a runaway, if not for the efforts of her, her sister and Dodenhoff's mother. 

"I knew, from the moment I began receiving messages about Christine, that she was no longer in this world," Vincent said.

The episode of Six Degrees of Murder on Christine Sheddy premiers on Wednesday, Aug. 3 at 10 p.m and re-airs Thursday at 1 p.m. and Friday at 6 p.m. on Investigation Discovery. Interviews with Dodenhoff and former Worcester County State's Attorney Joel Todd will also be featured.

SNOW HILL — A Texas man, now convicted twice for first-degree murder in the death of a Delaware woman in Pocomoke in 2007, was sentenced on Thursday to life in prison with all but 30 years suspended, bringing a measure of closure to the Worcester County homicide case that has been ongoing for eight years.

Justin Hadel, now 24, of College Station, Texas, was sentenced after pleading guilty to first-degree murder in March. Hadel was originally found guilty of first-degree murder for the beating death of Christine Sheddy, a 26-year-old Delaware woman reported missing in Pocomoke in November 2007. Hadel was sentenced at that time to life in prison without the possibility of parole, but filed an appeal seeking to overturn his conviction on a variety of reasons.

First and foremost, he claimed his conviction should be overturned because he was denied the opportunity to change his lawyer just four days before his scheduled trial. The Court of Special Appeals upheld Hadel’s conviction, but he filed a second appeal with the higher Court of Appeals, which overturned the Worcester County Circuit Court conviction and remanded the case back to Circuit Court for a new trial.

In March, Hadel decided to forego another lengthy trial and instead agreed to plead guilty to first-degree murder. The plea spared the expense of a second trial and the emotional toll it would have taken on the victim’s family.

Sheddy, a single mother, was first reported missing in November 2007 from the farm in Pocomoke. Sheddy had moved to the Byrd Rd. residence just about two months earlier and shared the residence with another couple Clarence “Junior” Jackson and Tia Johnson, along with Johnson’s two children, and Hadel, who is Johnson’s cousin. Sheddy was reported missing on November 13, 2007, touching off a massive search in the area of the Byrd Rd. residence where she had been living with her two young children.

After an extensive two-year search, Sheddy’s remains were discovered buried on the grounds of the River House Bed and Breakfast in Snow Hill, where both Jackson and Johnson had worked prior to Sheddy’s disappearance. The Office of the Chief Medical Examiner later ruled Sheddy had been killed by as many as four blows from a blunt object. Investigators identified Hadel as the suspect and he was arrested in Texas, where he had eventually returned to his family after Sheddy’s disappearance, and was charged with first-degree murder.

Johnson testified during the initial trial she had returned to the Byrd Rd. residence on the evening of November 13, 2007, to find the typical bonfire blazing on the property with no one else around. Hadel and Jackson returned a short time later and told Johnson that Sheddy had run off.

Johnson made arrangements for Sheddy’s children to be picked up, while Hadel and Jackson went to search for Sheddy. The two men returned about two hours later and the three adults and Johnson’s two children packed some belongings and inexplicably went to the River House in Snow Hill for the night. Sheddy’s remains were found buried on the grounds of the River House in February 2010 after a tip to investigators from an anonymous source.

During the trial, testimony showed Hadel had struck Sheddy as many as four times with a blunt object during a dispute over sex. Johnson testified Hadel had been intimate with Sheddy after she came to live at the Byrd Rd. residence. It also became apparent Jackson and Johnson were involved in the cover-up, although the extent of how much Johnson knew and when she knew it was not entirely clear.

What is clear is that Hadel eventually confessed to Johnson while the two were in a car together at a gas station in Salisbury after two earlier attempts to tell his cousin what happened that night. By the end of the initial trial, it was clear Jackson and Johnson were involved, at least in the cover-up, but the guilt for Sheddy’s death was squarely on Hadel.

At the initial trial, prosecutors argued Hadel intended to kill Sheddy and had enough time to reconsider before hitting her four times. The defense attorney argued for a first-degree assault conviction, asserting Hadel was a pawn in a larger cover-up constructed by Jackson and presumably Johnson.

Jackson was found to have a role in the murder and admitted being the ringleader and mastermind behind the cover-up. He was ultimately convicted of first-degree murder and was sentenced to life in prison with all but 30 years suspended.

For her part, Johnson knew more about the murder than she originally admitted and drove to the River House bed-and-breakfast in Snow Hill knowing Sheddy’s remains were in the trunk and waited while Hadel and Jackson buried the victim on the facility’s grounds. Johnson pleaded guilty in October 2012 to accessory after the fact and was sentenced to five years in jail for her role in the cover-up of Sheddy’s murder.
