Update: Smyrna Man Who Went Missing in Dunwoody is Located

Police located a man who went missing after a family dinner in Dunwoody Sunday near the Hartsfield-Jackson airport.

Andrew Charles Lichtenstadter, a mentally challenged 21-year-old, was found Monday. Dunwoody Police say they don't know how he had traveled to the airport.

The man was transported to Grady hospital. 

His family was especially worried because the man is on medication that he didn't have with him when he walked out of a restaurant on Ashford Dunwoody Road. 

Lichtenstadter is living at a residential group home in Smyrna, according to police. 

Lichtenstadter apparently became upset Sunday during a family dinner and walked out of the restaurant. The family left him on his own while he cooled off, police say. When they went outside to look for him, he was gone.
