Has this been posted already? I apologize, if so.
It is an update I came across, from Michelle Sigona's website (dated June 24, 2010).
"I spoke with Lt. Chris Mealey from the Thurston County Sheriff’s Office this morning and he said, “It’s still an open case and if we get information we will move on it as quickly as we can.” He also said that the leads have fizzled out and there is a chance she went into the water with her son, but they have no official confirmation on that."
Other than that, I don't think there was anything new, that I could see.
I still check here to see if there is any news. Oh, Shantina---where are you??
