SCREVEN CO., GA (WTOC) - It's been over a month since family or friends have seen Joel Landrum Fields.
The 57 year old was last seen at a construction job site in Screven County.
He left to go to a doctor's appointment and hasn't been seen or heard from since.
His sister says he would never disappear.
"That is something he doesn't do. He is going to call one of his sisters everyday. He is going to check on us or call and he didn't call," said Phoenicia Fields of Springfield, Georgia.
Fields said she has been calling her brother for over a month now and it just goes straight to voicemail.
Another reason they're concerned is because he has diabetes and needs insulin.
If you have any idea where he might be, call the Screven County Sheriff's Office.
