Prosecutors painted a nightmare scenario inside the family's Quakertown home. They said Sara Packer hated Grace and watched as Sullivan sexually assaulted and strangled her in a hot attic outside Philadelphia in July 2016, and helped hack up her body and dispose of it months later.
In a confession to police, Sullivan said he and Sara Packer plotted Grace's death. Sullivan admitted he punched and raped Grace as Sara Packer watched, bound her hands and feet with zip ties and stuffed a ball gag in her mouth.
“I got wrapped up in Jake’s fantasy,” Sara Packer said. “I didn’t think I could tell him no without losing him.”
