In the new Investigation Discovery series, Caylee Anthony’s grandmother, Cindy Anthony, is featured front and center. In one clip, Cindy is filmed having a sit down with the crime scene investigator to Caylee’s case, Alina Burroughs. “I know you guys didn’t want to leave until you found every single [bone],” she told tearfully told Burroughs. “It means a lot.”

That sit-down, however, proved to be quite a surprise for Burroughs. “I didn’t know how Cindy was going to react to me. I mean, I was a prosecution witness, so she could’ve seen me as someone who wanted to lock her daughter up,” Burroughs exclusively told People ahead of the premiere about her encounter with Cindy. “But she was very gracious. And I think in some ways, the interview gave her some closure.” She went on to add, “It’s hard for her to speak out about this case. She really went through hell and back, and she’s never been the same.”
