TUCSON - The Tucson Police Department says that they have secured the Celis house during their search for missing 6-year-old Isabel Celis.

In a press conference held at 2 p.m. today, Tucson Police Chief Roberto Villasenor said that they plan to get a search warrant to go back in to look for more evidence, saying that consent to search the home by the family could be questioned at a later date. Villasenor said that the family has cooperated fully with the investigation.

"The reality of the situation is that these are painstaking police investigations that are very complex, they require a lot of good old fashioned police work - dredging through the details," Chief Villasenor said.

Chief Villasenor said that in addition to the FBI providing two specialized search dogs, they have also brought in their Behavioral Analysis Unit, which "provides insight on what to look for in an individual."
The FBI's search dog did "alert" on a scent sometime between late last night and early this morning but Tucson Police would not provide any details at this time.

Police have also secured the landfill where the neighborhood's trash would have been dropped off, and are searching for possible leads there.

"I'm hoping my best that the child is alive," Chief Villasenor said. "We're going to work on the premise that the child is alive until proven otherwise. We want to remain hopeful. We want Isabel to return home safely."

The Chief of Police is asking for anyone who may have a lead in the case to call 88-CRIME or 911. For more on the search for Isabel, please continue to follow us at the link below.
