Two Fayette County women accused of killing a 9-year-old girl are facing more charges after police said they abused other children, beating an 11-year-old girl and starving a 6-year-old boy to the point where doctors said he's "so malnourished that eating could cause his death," according to court paperwork. 

Sarah Shipley and Kourtney Eutsey are facing a slew of new charges, including aggravated assault, endangering the welfare of children, simple assault and harassment, court records showed on Monday. 

The investigation into the two women began last week after 9-year-old Renesmay Eutsey was reported missing from a home on Third Street in the borough of Dunbar. Her body was later found in the Youghiogheny River. Four other children were pulled from the home. 

Both Shipley and Kourtney Eutsey were charged with homicide in Renesmay Eutsey's death, and prosecutors have been anticipating additional charges. 

Court paperwork details disturbing allegations 

According to the criminal complaint, an 11-year-old girl told police that Sarah Shipley and Kourtney Eutsey, whom she called "mom" and "dad," would beat her and choke her until she passed out. 

She described other physical and verbal abuse, telling police that she couldn't eat if she didn't do her chores and when she complained about a toothache, instead of making a dentist appointment, the two adults pulled it out with pliers. 

Also during the investigation, a 6-year-old boy was taken to the hospital for "significant malnourishment." Police said the boy was only the size of a toddler, weighed 24 pounds and had multiple abrasions and bruises.

A doctor told police that the boy needs to be treated for the potential of re-feeding syndrome, which is a sometimes fatal complication. She said the boy "is so emaciated and so malnourished that eating again could cause his death," police wrote in the criminal complaint.

Calling it "torture," police said the doctor told them the boy was suffering from "deliberate and chronic neglect." Investigators said the boy also had teeth that had been removed with pliers.  

DA calls alleged abuse "systemic" 

"What we've seen appears to be intentional, completely intentional, very systemic and over the course of a very long amount of time," said Fayette County District Attorney Mike Aubele.

Aubele says the abuse wasn't just hidden, it was actively concealed. He said Kourtney Eutsey and Sarah Shipley went out of their way to keep all the children isolated, cutting them off from professionals who might have noticed the warning signs. He said the children were also homeschooled. 

"Unfortunately, there were probably multiple family members, friends, acquaintances that had access to these children during that time and we received no reports," Aubele said. 

As the scope of this case widens, Aubele says his work is far from over. He insists his office will pursue every lead, examine every piece of evidence and make sure those responsible will face the harshest consequences. 

"No stone will be left unturned. We will find everybody responsible in this case," Aubele said. 

The 6-year-old boy remains in the hospital in stable condition. The girl, boy and two other children have been placed in foster care.
