I think Utah Girl posted a short article from (maybe) the Deseret News, about Lois Smart being interviewed for 3 or 4 hours by FBI. But I don't remember where or when (sounds like a song); If it wasn't Utah Girl, it was someone on this thread.
Police reviewing clues in Elizabeth Smart case
Salt Lake police have been going back over early clues in the Elizabeth Smart kidnapping, and they interviewed Elizabeth's mother last week. They have been going back through a list of people the family knew in hopes of finding new clues in the 3 1/2-month-old kidnapping.
As part of their plan to go back to square one and re-examine the disappearance of 14-year-old Elizabeth, police have returned to the Federal Heights neighborhood looking for more clues, said Elizabeth's father, Ed Smart.
Smart family spokesman Chris Thomas said that within the past few weeks, police have conducted separate interviews with both of Elizabeth's parents. Lois' interview last week lasted two to three hours and was meant to help police review the family's extensive list of friends, associates and workers who knew the family or had access to their million-dollar residence.
This clarifies that it was SLCPD who conducted the new interviews, not FBI. Evidently, they are not satisfied with what the family told them in previous interviews. Who is holding back information, and why? I also wonder if Mary Katherine has been re-interviewed, and whether or not she has revised her earlier story.
