72-year-old Dennis Hanson was found just before 5 p.m. Thursday after having been reported missing Monday morning.
Austin Police Chief Brian Krueger says Hanson was found hiding behind a couch in the basement of his home.
Hanson was able to walk out of the home on 3rd Avenue Southeast on his own and get into an ambulance for treatment at Mayo Clinic Health System-Austin.
Chief Krueger says Hanson appeared to be disoriented and the basement was cluttered.
The family released a letter today thanking everyone who helped out in the search efforts.
The letter also talked about depression and Hanson dealing with a struggle for "peace of mind."
It reads in part:
"It is our hope that everyone will have a renewed awareness of the magnitude a 'little down in the dumps' can have on a human mind. Depression is VERY REAL and NOT a CHOICE...
Dennis is but just one in our small space on earth, who at this very moment, is dealing with thought sand actions of this nature. Let us all remember how a community working together with such vigor can be a very real help to humanity. Treating our brothers and sisters with kindness and understanding is a HUGE part in their total care and recovery."
Chief Krueger says it's not known if Hanson was in the basement all along.
He does note, however, that family and officers had searched the home Monday.
