Crime / Cindy Anthony Dad: Here's How I Think Casey Killed Caylee His theory: She pumped Caylee full of drugs so she could party By Kate Seamons, Newser Staff Posted Sep 15, 2011 9:23 AM CDT Copied In this Aug. 3, 2011, image released by CBS Television Distribution, from left, Cindy Anthony and George Anthony, parents of 25-year-old Casey Anthony, are shown during an interview.

Mom, for her part, believes there's a kernel of truth to the drowning story put forth by the defense. "I buy the part that Caylee drowned, but I don't buy the circumstances surrounding the drowning." George was a little more damning in his opinion. "I believe something else happened to her. ... I believe Casey or someone else she was with possibly gave too much to Caylee. She fell asleep and didn't wake up." When McGraw asked what "too much" referred to, George replied, "Possibly some kind of drug or something like that." Why would she have drugged up Caylee? To "go out and have a good time. To be with friends." The Huffington Post notes that Cindy looked shaken by his answer. "This is the first time that I've heard this out of his mouth. I'm really kind of shocked to hear that today." (More Cindy Anthony stories.) See 1 more photo Report an error
