Friday they trampled through thick brush and dense farmland in Granville County looking for any sign of the missing mother.
Pat Currin, Morris' father said his daughter is a devoted mother and never far from her two daughters.
Absolutely not," said Pat Currin, "She would not leave her children. She would never leave them without calling or letting someone know."
A mysterious fire at the home Kelly Morris shared with her husband and children has raised more questions than answers. Investigators won't say if the fire and Morris' disappearance are related. Investigators said their home burned last Thursday while her husband Scott was at work and their children were in school. The ATF and the SBI are investigating the cause of the fire. According to Sheriff David Smith, forensic test results are pending.
While firefighters responded to the fire, Morris' 2005 Honda Accord with her keys, purse and cell phone inside were discovered about a mile away in a new subdivision.
"She's not like that," said Currin, "She would never leave and not let us know."
Heavy rain over the weekend hindered search efforts. About two dozen volunteers have tried to make up for lost time by searching several miles surrounding the Morris home on foot, horseback, motorcycles and on all-terrain vehicles.
There are seven detectives in the Granville County Sheriff's Department. Six are now assigned full-time to the Morris case.
Investigators are urging the public to report any helpful information at (919) 693-3100.
