Please Help

I know that there are not many people (if any) who view this blog. But, I still hope that this can help even a little bit. My cousin's daughter and her boyfriend (both are 15) are missing. They are suspected as runaways and have stolen 2 vehicles. The vehicle they are thought to be in now is a 1996 Blue Dodge Neon with a license plate Y097DG. They are thought to be heading to Salt Lake City, UT. And stole the Neon from Ephraim, UT. Any help would be greatly appreciated.
