KAKE News has exclusive information and explosive allegations
against a Geuda Springs woman accused of killing her newborn baby.

A judge declared Rebecca Gregory incompetent to stand trial. Now, a woman close to Gregory reveals startling details of the alleged baby killing.

A cellmate of the accused woman tells KAKE about secret conversations and a confession she heard.

Former cellmate Sabrina Osborne says Gregory told her she delivered the baby at home.

Osborne says, "She said the baby was crying and she was stressed out so she put a sock in his mouth and a pillow over his face."

Sabrina Osborne spent five weeks in a small cell with Gregory. Osborn says Gregory wouldn't talk about what happened at first, but eventually claimed Gregory confided in her, and explained in detail the murder of her baby boy.

Investigators have never revealed how they believe Rebecca Gregory killer her newborn son. But now, these alleged details may never be heard in open court.

Thursday in court, she was declared incompetent to stand trial for the murder of her newborn baby. Rather than returning to her jail cell, Rebecca Gregory will return to the Larned State Hospital for at least 90 days.

But while mental health officials might believe Gregory doesn't understand her actions or the charges against her, Osborne disagrees.

Osborne says Gregory told her she hid her pregnancy from her family and delivered the baby at home alone. But Gregory has another son, so why hide this pregnancy? The reason, according to Osborne is a startling secret Gregory wanted to hide.

Osborne says Gregory told her her brother was the baby's father. And Osborne says Gregory's secret did not stop there, and Gregory had help covering up the murder.

Osborne says, "She said she called her dad and he said he'd come pick it up and he took it to the pig farm."

Gregory lived on a pig farm with her parents and two year old son. According to court records, investigators found what they believed to be human bone fragments in a burn pit on Gregory's property.

Osborn was in court when the judge read the ruling declaring Gregory incompetent. She agrees Gregory has some psychological problems. But Osborne still believes Gregory should stand trial.
