People go missing for a variety of reasons and with all the cutbacks to police departments, most law enforcement agencies are working at minimum or below minimum staffing, which translates to less officers and detectives working full time on missing person cases. At Corsi Investigations, we have a vast network of contacts within the law enforcement community and SAR (search and rescue teams). We can work with state and local law enforcement agencies to assist in expediting to locate the missing person. Let Corsi Investigations assist the police from the start of the missing person case before any leads run cold. Some reasons for launching a missing persons investigation are:

  • Locating family members or long lost loved ones

  • Debtors

  • Runaways and minors suspected of being kidnapped

  • Missing persons who are now classified as a cold case



Your Satisfaction is Our Priority

We will maintain contact and inform you of the status of your case.  We have a very distinct area that we investigate, if your case requires areas that is not best suited for us to assist you, we will gladly refer you to another reputable agency best suited for your needs.
