Weintraub said that although Sullivan's statement cannot be used against Packer, investigators have a strong case alleging that she was complicit in the plot to kill the girl, who she adopted as a toddler. Packer purchased sedatives allegedly used in an attempt to poison her daughter and the bow saw allegedly used to remove her limbs, court documents say. She also stored the body for three months packed in kitty litter in an attic closet one floor above her bedroom, authorities allege.
