Henry Blackaby was found Friday evening after going missing for over 24 hours.
"Henry Blackaby update: He has been found! Doctors are checking him to see if he is OK, but he is safe. THANK YOU for your prayers!," his son Richard Blackaby tweeted around 9 p.m.
Earlier in the day Richard wrote that hundreds of volunteers joined police in their search for his father, who is 78 and a diabetic. Henry’s debit card was used in a city about an hour and half south of their home in Atlanta, he said.
