The search continues for 19-year-old Elizabeth Garrow-McDonald.
She was last seen on Wednesday at the Dunkin' in Canastota.
More than 100 people showed up to help form search parties.
The Madison County Sheriff told Spectrum News that they were searching a "substantial piece of land" Saturday after some electronic data pointed them to a few specific areas.
No evidence was found during the search, but the sheriff says some important evidence was located Friday.
The sheriff said Garrow's husband is in police custody on a court order violation.
He has invoked his right to an attorney, but the sheriff hasn't confirmed if he's a person of interest in the case.
Overall, deputies say they are remaining hopeful.
"I'm the same as anybody else, I want to find her alive. That's what we do, we want to save lives in law enforcement. I hope it doesn't turn that way, but we've dealt with this before, it could turn that way. So, we're waiting to take in information that tells us otherwise. Until then, we're pushing forward with the investigation to find her," said Madison County Sheriff Todd Hood.
The sheriff says the search will continue Sunday.
Spectrum News is told Garrow has a 1-year-old daughter, and is expecting a second child.
Anyone with information is asked to contact the Madison County Sheriff's Office.
