This cold case is one which should be in the jurisdiction and purview of the Michigan State Police, since Paige was last known to be traveling by car from the airport to her home, and last seen on a highway. It would be nice to know what priority her case has been assigned for investigation. Here is the official Michigan State Police policy regarding cold cases:
The Michigan State Police Cold Case Unit determines which cases will be officially reopened by using a scoring matrix. The matrix is comprised of several factors which determine each case's solvability rating. Even though all cold cases will be reviewed, not all of them may be reopened for investigation.
