The Martins Ferry couple accused of contributing to their infant son's death have a shocking history of child endangerment.

Documents from the Allegheny County Court of Common Pleas revealed that Ciejae Winslow, the father accused in the death of his 6-week-old son, pleaded guilty to endangering the welfare of another child in 2001.

Further, Christine Osborne Winslow, the mother involved in this case, also pleaded guilty to charges of endangering the welfare of a child.

The complaint said the parents are responsible for throwing a two-month-old girl up in the air and "mugging" her in the face. The complaint further said the two put hot sauce in the baby's mouth, and the infant had bite marks, bruises, fractures and even burn marks on her body.

Just like in the case in Belmont County, the Winslows were accused of neglecting to obtain treatment for the child.

That child was immediately put in foster care. However, the pair did not spend a single day in jail. Instead, they received five years probation.

Belmont County Prosecutor Chris Berhalter said he is aware of this information. He said the Winslows' criminal history is all part of the investigation into whether or not they let their six-week-old die in Martins Ferry.

"We were aware of the facts of the case in Pennsylvania, and I believe that's what motivated us to make sure that it ended here," Berhalter said.

Dwayne Pielech, of Belmont County Department of Job and Family Services, said the department did know about the Winslows' history.

He said they were notified by Allegheny County Protective Services and immediately decided to assign early childhood development programming. The Winslows were in the system for about eight months.

Officials said after those months of supervision, it appeared that the Winslows learned their lesson from the incident in Pennsylvania and were on the right track toward becoming responsible parents.

"There had not been any signs of any problems or any type of abuse. After a six to eight month period, our agency basically closed the case because they were working with the early childhood development people," Pielech said.

Because of their history, the Winslows stayed under periodic supervision with the other early childhood development agency until Ciejae Jr.'s death. Pielech said this tragedy is still something no one could have predicted.

Pielech also said that, as soon as the infant's death was ruled suspicious, the state was called in to investigate if there was any oversight by children's services in Belmont County. That report came back clear.
