Caylee Anthony mom is infamous as Casey Anthony, but I was wondering what happened to her Daddy? It turns out that family has suffered even more tragedy. It may be that Michael Patrick Duggan, a man from Cape Cod, fathered Caylee. He was killed in 2007 in a car crash on Cape Cod. Whether or not he is the father is a question his mother has. She would like to know. What a horrible set of circumstances.
