From Nancy Grace again................the mother of Michael Duggan was interviewed by Nancy. Her name is Donna Maclean. She said the other side of the family (husband's) had family in Orlando and took her children to Orlando to Disney World on frequent vacations when they were young, so there's a connection to Orlando.
At the time that Caylee would have been conceived, her son, Michael was 21. He was working in Tennessee. In a phone conversation with his mom (Donna) he told her that his girlfriend was pregnant and they were having a girl. He went on to mention his girlfriend's family mentioning the names, Cindy, George, Casey, and said the father was a cop.
Michael Duggan was killed in a car accident in 2007.
Mark Lippman, says his office has been contacted about this matter and that Donna can have a DNA test done if she has something from her son. Donna Maclean says she doesn't have anything of her son. But an attorney said they can do DNA from Donna - micondonal (spelling) DNA.
