Sara Packer then left and obtained several pills. Sullivan and Sara Packer then gave Grace the pills, telling her it would help her deal with the pain, tied her up, gagged her and then left her to die in the extremely hot attic.

The teen was still conscious and alive. Sullivan then wrapped his arm around Grace’s neck and face and stranguled her to death. Sullivan and Sara Packer then packed her body in kitty litter.

On July 11, 2016 Sara Packer went to the Abington Police Department and reported Grace was missing. Sara allegedly lied to police and told them she sent Grace to her room following an argument over the teen asking to visit one of her friends. Police noted that Sara couldn’t provide an address or name of the friend. ^{[5] [4]}

Sara Packer also allegedly told police Grace took $300 in cash from the home and that she had left the house in the past.

Police then made several attempts to reach Sara Packer as they searched for Grace over the next two months.

Sara allegedly ignored them and was uncooperative with the investigation.

Police then visited Sara’s Abington Township home on September 7, 2016, but discovered she had moved without notifying them.

Police then learned Sara Packer had enrolled her 12-year-old adopted son, who is also Grace’s biological brother, into the Quakertown School District without notifying them.

Police then received a phone message from Sara apologizing to them for not notifying them of the move.

Sara Packer also allegedly told them she had notified all of Grace’s relatives that she went missing.

Investigators later determined she had not told her relatives about Grace's disappearance at that time however.

Police then investigated the Quakertown home where Grace's body was being concealed in mid-October.

It was at this time when Sullivan allegedly became concerned investigators would find the girl’s remains.

Sullivan and Sara Packer then moved Grace’s body from the attic to the second floor bathroom of the house and used a saw to dismember her limbs. ^{[5] [4]}

The duo then allegedly stored her remains in plastic totes and put them inside the trunk of Sullivan’s vehicle.

They then drove to a wooded area near SR 2041, White Haven Road in Bear Creek Township, Luzerne County, Pennsylvania where they left Grace's remains.

On October 31, around 5:30 p.m., hunters in the woods found the remains and called police.

On December 30, 2016, Sullivan and Packer overdosed on pills in a failed suicide attempt. A woman from Sullivan's residence called police when she found him barley conscious and unresponsive.
