Volunteers continued searching for Tricia Todd Wednesday.
They covered an area of U.S. 1 in Hobe Sound from SE Poinciana Lane south to SE Pine Circle.
The Martin County Sheriff's Office suspended its ground search for Todd Tuesday.
Todd was reported missing two weeks ago when she didn't pick up her young daughter.
The sheriff's office says there is still no evidence that a crime took place or that Todd was abducted or left the area on her own.
Volunteers are also asking the public to share a new flier which was posted on Facebook.
The flier asks everyone to be on the lookout for the shell necklace Todd was wearing as well as her iPhone and pink wallet that are missing from her car.
