A North Dakota woman, Brooke Crews, was convicted for killing her pregnant neighbor, 22-year-old Savana Greywind, on Tuesday. She told the court that she cut out Greywind's unborn fetus because her boyfriend pressured her to "produce a baby," according to reports.

Crew's boyfriend, William Hoehn, who has been charged with the conspiracy to commit murder, during an earlier trial had revealed that he tightened a rope around 8-month pregnant Greywind, while his girlfriend Brooke Crews slit her stomach open and tore the baby out of her womb.  Reports state that Greywind was eight months pregnant when authorities found her body wrapped dumped in Red River, North Dakota, wrapped in plastic last August. Crews, who confessed to kidnapping and murdering, the 22-year-old was sentenced to life imprisonment without parole in February.

Crews, during the trial of her boyfriend on Tuesday, gave a chilling testimony, saying that although she never "explicitly" shared her plan to kidnap Greywind, he had given her "an ultimatum" to "produce a baby" after it became evident to him that she lied about being pregnant, according to Huffington Post.  Hoehn admitted to helping Crews cover up the murder, however, he claimed that he did not know she was planning to kidnap and kill Greywind to take the baby.

"I took that to mean I better have a baby, no matter how it happened," Crews said during the testimony.

Crews claimed that she pushed Greywind over a flight of stairs, which knocked her out, it was then when she began cutting the fetus out of Greywind with a knife. A medical examiner, however, testified and said that there was no evidence on the victim's body of any head injuries, according to reports.

Hoehn claimed that when came home and entered the bathroom, he saw Crews cleaning up the blood from the bathroom floor and she presented him with an infant girl, saying, "This is our baby. This is our family."

Hoen admitted to disposing off Greywind's bloody shoes, towels in a garbage bag far away from their apartment and he added that when Crews told him she wasn't certain if the 22-year-old was dead, he took a rope and tightened it around her neck to choke her and said, "If she's not dead, she is now," according to Daily Mail.

Reports state that the baby girl survived the gruesome attack is being raised by the slain girl's boyfriend, who has full custody of the baby.
