Authorities say two family members did their research and created a plan before they brought a pregnant woman into their home, put her into a car and then took her to an area in the northern Michigan woods — where they forced her on the ground and stabbed her as they cut her baby out of her womb, ultimately causing both of their deaths.

Then, the pair left 22-year-old Rebecca Park there, Wexford County Prosecutor Johanna Carey said during an arraignment on Tuesday, Dec. 2, in Cadillac of Cortney Bartholomew, 40, and Bradly Bartholomew, 47.

The pair, described by the Cadillac News as Park's biological mother and stepfather, were charged with the following: one count of first-degree premeditated murder and one count of felony murder in connection with Park's death, torture in a place of confinement, conspiracy to commit torture, assault of a pregnant woman with the intention to cause miscarriage or stillbirth, conspiracy to commit that assault and unlawful imprisonment. Both were additionally charged with moving a dead body.

"This is, frankly, evil personified," Carey said.

Carey said that Park's baby died. No other details were immediately available after the arraignment. The Wexford County Prosecutor's Office declined to comment after the court hearing.
