Fatal Family Feuds season 2 episode 7: What happened to Pauline Devor?

When Bob Devor returned from a business trip on June 15, 2007, he found his Arkansas house had been robbed and that his wife, 70-year-old Pauline Devor, was missing. He called 911 to inform them about her disappearance and also reported that $7000 as well as 14 guns were missing from the home.
The authorities who arrived at the scene and investigated the crime discovered two bullet holes in a wall. However, that was all they found, and while they did continue the investigation into Pauline's disappearance, they didn't find a lot of evidence.
The case went cold for two years when a woman named Monica Bautista reached out to them in 2009. She admitted to having been involved in Pauline Devor's murder with Delores Jean Eggert, Pauline's daughter and Bob's step-daughter.
Delores, who was 47 at the time, reportedly had a strained relationship with her mother, as explored on Fatal Family Feuds. Monica told the police that she and Eggert persuaded Pauline to visit a farm in Northwest Washington County.
She confessed that at the rural location, Delores tried to shoot her mother, but after the gun jammed, the two women got into a fight, and Monica hit Polly in the head with a stick. She added that Delores then used a tire iron to beat her mother unconscious before getting another weapon and shooting her three times in the chest.
Monica also directed them towards the Devor family ranch in April 2009, where they located Pauline's remains, as shown on Fatal Family Feuds. The farm was located in Northwest Washington County near Cincinnati, and had human remains, including parts of the skeleton and dental crowns belonging to Pauline Devor.
Delores Jean Eggert had a s*xual relationship with her stepfather, Bob Devor

As authorities dove deeper into Delores Jean Eggert's life, they discovered that she'd had a s*xual relationship with her mother's husband, Bob Devor, a year before Pauline's death.
Amy Driver, the Deputy Prosecutor, Washington County Prosecutor's office, claimed that Delores only had the affair with Bob due to her "anger and hatred towards her mother, according to Oxygen.
The publication also quoted Senior Deputy Prosecutor for the Washington County Prosecutor's Office, Denis Dean, discussing why Bob would want his wife dead. Dean stated that Bob was "tired of Polly's gambling habits" and her "reckless spending." He added that Bob Devor was "afraid that the family fortune was going to be depleted if Polly remained alive."

After Monica Bautista admitted her involvement in the murder in 2009, they tapped her with a voice recorder. As per the official case file, when Monica met her at a Walmart parking lot on April 13, 2009, Delores encouraged her to stick to her earlier story. Delores also said that her step-father would hire an attorney for her.
When the authorities tapped into Delores' phone, they heard her saying to a woman that she had dumped some of Pauline's remains in a river.
