AURORA -- The owner of a house where Aarone Thompson and her family lived toured the two-story home with police officers on Wednesday to see if any changes have been made to the walls or any other part of the structure since the Thompson family moved in.

Aarone was reported missing on Nov. 14 by her father. Police said they investigated the case as a missing person but concluded that she was likely killed more than a year ago. A tip from a source, whom police say is close to the family, led investigators back to the house.

On Wednesday, police focused their efforts on the crawl space and basement of the family home on East Kepner Place. During the tour, police were hoping that the homeowner, Jasbir Singh, could point out recent modifications to the structure, including if there has been new paint or new carpet.

But Singh emerged from the home Wednesday night and told reporters that he didn't notice anything out of the ordinary. He said that the Thompsons were good tenants, and had been the last four years they were renting from him.

Earlier in the day, the utility companies were out at the home, marking water and gas lines, in what police say is preparation for more intense digging around the home. Officers plan to continue with the archeological digging in the back yard. That is expected to resume on Saturday, 7NEWS reported.

Supporters of the girl's father, Aaron Thompson, are putting together a volunteer search party that will once again go out in the neighborhood Friday morning to look for the girl. They will post flyers and talk to neighbors, 7NEWS reported.

These volunteers stand behind the father and his claim that his youngest daughter got mad and ran away from home more than 10 days ago.

Aaron Thompson and his live-in girlfriend, Shely Lowe, are considered "persons of interest," but they are still refusing to be interviewed by investigators, police said.

A spiritual advisor for the Thompson family said that the family is willing to do anything to help find the missing girl. But, when an Aurora police detective interrupted the family's news conference on Tuesday to ask if the couple could come down to the police station for interviews and polygraphs, the advisor said police had already had their chance to talk to them.

Police have also asked Thompson to volunteer for a polygraph but he declined, police said.

"There's already been several new facts that have come to light to us that we need to ask them about. There's some inconsistencies in what they have been telling us," Aurora police spokesman Marcus Dudley said.

The family has questioned why police aren't searching for the girl and instead are going on a "fishing expedition" in the family's back yard.

Police responded by saying they are still actively searching for Aarone but they hold firm to their belief that the girl is no longer alive and nothing has occurred that would change that belief. In fact, what they've learned so far has only strengthened their belief that the child was killed, perhaps months ago, Dudley said.

"Up to this point, no one other than the parent that reported her missing has been able to substantiate that she has still been around this area, or at least in that house, within the past year and a half," Dudley said.

Officers plan to be searching the Aurora home for another week.
