A woman accused of killing her 14-year-old adoptive daughter in a “rape-murder” fantasy previously worked as an adoption supervisor in Pennsylvania before being suspended in 2010, officials announced Monday.

Sara Packer, 41, worked as a supervisor for the Northampton County Children and Youth’s adoption department from 2003 until January 2010, earning $44,662 at the time, County Controller Stephen Barron Jr. said.

“I have asked them to investigate this situation to be sure that no other children are at risk based on actions Ms. Packer took while employed with the county,” Barron said in an email to The Post.

“Packer was suspended without pay on Jan. 20, 2010,” Barron said, without elaborating.

Northampton County District Attorney John Morganelli said his office is not investigating Packer because there are no allegations against her at this point, the Allentown Morning Call reported.

Packer and her boyfriend, Jacob Sullivan, 44, were charged Sunday with homicide, rape, conspiracy, kidnapping and abuse of a corpse over the July death of 14-year-old Grace Packer, who was reported missing last summer.

“Unfortunately, Grace Packer was a disposable child to these people,” Bucks County District Attorney Matthew Weintraub said in a statement. “Who will now speak for Grace Packer? We will.”

Both Packer and her former husband, David Packer, 40, had lived in several locations throughout Pennsylvania, including Allentown, Lehigh Valley and Emmaus, the newspaper reports, citing public records. The couple had divorced in June.

The newspaper reports that David Warren Packer was charged by police in Allentown in two separate child sex abuse cases. He pleaded guilty to indecent assault and statutory sexual assault in both cases. He was sentenced to six months to five years in prison and was required to register as a sexually violent predator.

Investigators have said Packer and Sullivan used cat litter to mask decomposition smells of the teen’s body, which they stored in the attic before dismembering it in October after being scared by a visit from police. The girl’s torso was later found by hunters in a Luzerne County park on Oct. 31.

Sullivan and Packer did not enter pleas during their arraignments on Sunday and were denied bail. They were expected to be transferred to Bucks County Prison and are expected back in court on Jan. 20.

Weintraub said the teen was taken in as a foster child by Sara Packer when she was just 3 years old.

Sullivan, meanwhile, apologized to reporters as he was led into court, according to Weintraub.

“I’m sorry for what I did,” Sullivan said.
