Rebecca Park's Sister, Who Was Having Affair with the Slain Woman's Fiancé, Alleges Her Lover Confessed to the Crime

The sister of Rebecca Park told police that the pregnant mother's fiancé allegedly confessed to being involved in her killing.

Kimberly Park spoke with two detectives from the Wexford County Sheriff's Office on Nov. 25 after being taken into custody on charges of tampering with evidence, lying to a police officer and filing a false report.

She waived her Miranda rights, according to a copy of the probable cause affidavit filed in her case and obtained by PEOPLE, and allegedly said that she lied to protect her sister's fiancé.

"Kimberly Park identified that on Tuesday Nov. 4, 2025, while she was at Richard Falor's home, he told her that he killed Rebecca Park and that he wanted to protect Kimberly by not sharing details with her," Lt. Chris Piskor wrote in the affidavit.

Kimberly then went on to say that Falor allegedly told her that "something went wrong while trying to cut the baby out of Rebecca."

She hinted at this allegation earlier that same day while speaking with deputies in a non-custodial interview at her home following the discovery of Rebecca's body.

"[Kimberly] made a statement that Falor had told her that Rebecca had been taken care of and not to worry about it," Piskor wrote.

The affidavit further states that Kimberly alleged it was Falor who "told her to lie."

That was in reference to Piskor's interview with Kimberly on Nov. 22, when she "reported that Cortney and Brad[ly] [Bartholomew] had struck Rebecca Park in the head to cause her to have a seizure and when they were unable to revive Park from the seizure, Brad contacted a friend who came and picked up Rebecca Park's body and took it away," according to the affidavit.

Kimberly also allegedly told investigators that Falor told her to lie because of his concerns about "the investigation getting close to him."

It is also noted in the affidavit that during the investigation, on Nov. 24, Kimberly claimed that "she was and has been in a romantic relationship with Falor."

When her mother Cortney Bartholomew — who is married to Bradly — was interviewed just a few days after her own arrest, she too spoke about having an affair with Falor.

Kimberly Park spoke with investigators from the Wexford County Sheriff's Office throughout the investigation into her sister's murder. She was also the first person arrested in connection with the murder when she was booked into custody just hours after Rebecca' body was discovered in the Manistee National Forest on Nov. 25.

Piskor wrote in the affidavit that the man Kimberly identified as Falor's "co-conspirator" was taken in for questioning but released after showing investigators telephone records which placed him outside the county on Nov. 3 — the night of Rebecca's murder.

Falor requested a lawyer when investigators tried to question him and Kimberly did the same at her next interview, at which time both their interviews were terminated, according to the affidavit.

Kimberly was released a week after her arrest and is currently on house arrest after her bail was reduced from $750,000 to $5,000 last week.

Falor was also released at that same time after his own bail was reduced for the two drug charges he faces in an unrelated case. When asked if he was still a person of interest in the wake of Kimberly's claims, the Wexford County Prosecuting Attorney's Office declined to comment.

As Kimberly and Falor were leaving the jail, Cortney and Bradly were just arriving for a more extended stay.

Cortney and Bradly both face one count each of first-degree murder, felony murder, torture, conspiracy to commit torture, assault on a pregnant individual causing miscarriage/stillbirth and conspiracy to commit assault on a pregnant individual causing miscarriage/stillbirth.

Each of those six charges carries a possible life sentence in prison.

They are also charged with one count each of unlawful imprisonment and removal of a dead body.

According to prosecutors, it is alleged that on Nov. 3, the couple lured Park — Cortney's biological daughter, who was approximately 38 weeks pregnant at the time — to their Wexford County home, where they then "allegedly tortured Park in an attempt to remove the unborn infant, resulting in the death of both," per a press release earlier this month.

Bradly allegedly told officials that the couple could not adopt a child because he is a registered sex offender, according to the affidavit.

“This case involves a truly horrific homicide in which a young woman and her unborn child endured unimaginable suffering at the hands of the Defendants,” said Wexford County Prosecutor Johanna Carey, per the release. “The brutality and disregard for human life displayed here are deeply troubling. While these remain allegations until proven in court, the evidence reflects an extraordinary level of callousness and violence. We look forward to presenting the full facts in court.”
