Project Jason facilitates a unique missing persons program, targeted at the startling number of people who lose their homes and drift off the radar every year. You can find more information here.
From the Project Jason website:
There are an estimated 3.5 million people in the United States who experience homelessness each year. People may become homeless for varied reasons, which include mental illness, addictions, domestic abuse, poverty, trauma, and lack of affordable housing.
Project Jason's mission statement includes creating and increasing public awareness of missing persons. With an estimated 850,000 new cases per year, it remains a challenge to find avenues to reach all facets of society in an effort to locate missing persons. It is not known how many of the homeless may be reported missing persons, but it is a certainty that many are.
In order to reach this segment of the population, the Come Home program was created. The bi-monthly Come Home poster will feature all of the necessary data and contact information about a selected missing person. It will also include a personal message to the missing person from their family. They simply want their loved one to Come Home.
