With every poster, John Miller hopes he's closer to finding his 29-year-old daughter Catie.

Miller and a team of volunteers were out in north-end Dartmouth on Sunday to put up posters about his missing daughter.

"We know that although the poster campaign has gone well, we don't know where every poster is. So today we're focusing on north-end Dartmouth because that's where Catie lived," Miller said.

"We're trying to make sure that this area is very well covered."

Catie Miller's apartment is on Stairs Street, off Windmill Road.

Her parents hope that someone in the neighbourhood may have seen something on July 15 — the day she vanished.

Miller's family said she has some problems with depression, but it is out of character for her not to be in touch with them.

Police are treating it as a missing persons case and do not have any suspects.
