What do to if your Child is Missing provides parents with the most current information on, and helpful insights into, what families should do when a child is missing. The first edition of this Guide was written in 1998 by parents and family members who have experienced the disappearance of a child. It contains their combined advice concerning what to expect when a child is missing, what needs to be done, and where to go for help. It explains the role that various agencies and organizations play in the search for a missing child and discusses some of the important issues that need to be considered. The Guide is divided into seven chapters, each of which is structured to allow information to be found quickly and easily. Each chapter explains both the short- and long-term issues and contains a checklist and chapter summary for later reference. A list of recommended readings and a list of public and private resources appear at the back of the Guide. This third edition of the Guide was published in 2004.

It includes a section recommending actions with hiring a private investigator.

Over 76 million records of deceased persons.  Really cool for checking to see if someone is using a dead persons Social Security No.  Or, maybe the missing person or fugitive is dead.  When I worked fugitives we made this the first place our investigators checked.  A few times the reason the offender didn’t come to court is because they had an appointment with Satan.

The Federal Judicial Center reference manual on Scientific Evidence.  You may find this a helpful reference source when looking at the various types of sciences, how they are introduced and how Daubert applies.
