What is a one-sentence summary of the following article?
Call the people in the missing person's life and ask when they last saw him or her. Determine if they know anything about the person's whereabouts. Besides friends, family members, neighbors, and classmates, call anyone who had regular contact with the missing person. This may include teachers, doctors, dentists, bus drivers, coworkers, and neighbors. Keep a log of the people to whom you've spoken and what they had to say about the missing person. Keep it updated with as much detailed information as possible. Encourage people to call you back if they find out more information from another source. Report new findings to the case worker in charge of your missing person's case at the police department. If the missing person was in an accident, he or she might be in a local hospital and unable to communicate for some reason. In some tragic cases, a missing person will be found with a coroner or medical examiner. Call all the facilities in your area to rule out these possibilities. When you make the calls, ask for the missing person by name. If no one by that name is on record there, ask if they have unidentified people in their care who resemble your missing person. If the missing person had an encounter with law enforcement that led to an arrest, he or she may be in a local county jail. Check with local law enforcement offices to see if the missing person is incarcerated. You may also be able to check online using the "inmate locator" option on your local law enforcement's website. This is an important way to gain information about the days leading up to the person's disappearance. Check his or her Facebook, Twitter, Instagram, and other accounts. Determine whether recent activity contains any clues. Look at the missing person's friends' accounts as well. Print out correspondence and activity that seems as though it could lead to the missing person's location. Report any activity that might be a clue to the case worker at the police department. Often, the missing person will see the fliers and decide to return home. Fliers can also alert friends and neighbors who might have information about the person's whereabouts. Put up the fliers in the neighborhood where the missing person lived and around places where he or she spent time. Hang your fliers in prominent locations. Gas stations, grocery stores, post offices, banks, drug stores, local libraries, churches, hospitals, homeless shelters, parks, and hiking trails will all work well. Be sure to include a recent, clear photograph of the missing person. Include the person's age, a physical description, and the date he or she went missing. Include contact information as well.
Contact the person's friends and acquaintances. Check with hospitals and coroners in the area. Check with your local county jail. Check social media sites. Put up fliers with a picture and description of the missing person.
