I found this about that Nicole who was found murdered in Blanchard Park.
"Emergency response team members used machetes to cut through the brush in hopes of finding possible evidence. Deputies said they havent found a lot of items, but they did find a black baseball cap and the back of a cell phone charger. Detectives say they have no witnesses and believe everything they find is possible evidence."

We know Casey was at that park either that day, or the following two days. I searched threads here for this info, found nothing. Could the back of a cell phone found be for the missing blackjack phone Casey says she lost?
