Dozens of the Georgia Bureau of Investigation agents searched a pecan farm in the south Georgia town for Tara Grinstead’s remains on Tuesday.

A crew of more than 40 people were involved in the massive dig which lasted all day in the Ben Hill County. GBI Special Agent in Charge J.T. Ricketson said that, "there are agents from eight different GBI offices. I have five crime scene specialists here. We actually enlisted the services of two anthropologists in case we find any skeletal remains."

From the NewsChopper 2 at the scene, multiple tents and also dig areas were visible in the wooded area.

Ricketson said that the agents stood shoulder to shoulder and walked off some area. They then went to their hands and knees and crawled in that same area. We identified some specific areas which we gridded off so we can do a grid search .

Thomas learned that the agents were first told about the property last week, but just zeroed in on the specific locations on Tuesday. Ricketson said that since an arrest in the last week, interviews with the "people who were involved" led his team to the land. But, the landowner is not involved, he said.

Grinstead, a teacher and also a former beauty queen, was reported missing from her Ocilla home in the October 2005.

Last week, the Georgia Bureau of Investigation and also local Georgia authorities announced an arrest in the case. Ryan Alexander Duke was charged with the murder, burglary, aggravated assault and concealing a death.

The GBI said that someone walked into a sheriff's office earlier in the last week with information which led to several new interviews and an arrest.

Ricketson also said that, through these interviews, enough probable cause was discovered so we could swear out an arrest warrant charging Ryan Alexander Duke with the murder of the Tara Grinstead.

During the Duke's first court appearance, we heard for the first time authorities believe that Duke used his hands to kill Grinstead.
