Mom Charged With Rape and Murder of Adopted Daughter Worked at Child Welfare Agency

Sullivan apologized in court.

A Pennsylvania mother charged with killing and dismembering her 14-year-old adopted daughter previously worked as an adoption supervisor for a children's welfare agency, police have revealed.

Sara Packer worked as a supervisor for the Northampton County Children, Youth and Families Division for adoptions from 2003 to 2010, when she was suspended, reports said.

Packer and her boyfriend, Jacob Sullivan, have both been charged with criminal homicide, rape, and abuse of a corpse after they allegedly planned the crime for more than a year as part of a rape and murder fantasy the couple shared, police said. 

Grace Packer’s body was found dismembered on Halloween after she’d been missing for months.

Grace was allegedly drugged and then raped by Sullivan while her mother watched on July 8, police said.

Cops say she was then left to die, but when Sullivan saw that she was alive the next day, he allegedly strangled her. Packer then told police her daughter was missing and had run away after an argument, according to authorities.

After several unsuccessful attempts to contact Packer in September, investigators learned Grace and her 12-year-old brother, also adopted by Packer, had been withdrawn from Abington School District.

Authorities said Packer kept receiving her daughter's monthly $700 Social Security checks and updated disability forms in August without reporting the girl's disappearance.

Packer and Sullivan did not enter pleas and were both held without bond in court on Sunday.

Sullivan apologized as he was led into court, the Intelligencer newspaper reported.

"I'm sorry for what I did," Sullivan reportedly said. "It was wrong."
