TUCSON - At the 8 p.m. news conference about the disappearance of Isabel Celis, Tucson Police announced that investigators completed the search of the landfill for the day at about 4:30 p.m. The search will continue Tuesday morning at 6 a.m. and is expected to wrap up about 2:30p.m., at which time police will announce if anything significant was found.

Meanwhile, detectives will remain on the scene throughout the night, including some who will continue to make contact with those living in the neighborhood who may not have been home during the first days of the search for Isabel.

Tucson Police did say officers, as a matter of normal procedure are searching the area for surveillance video that might help them in this case, but would not say if they have found any at this time.

TPD also said a second search of the Celis property Monday was prompted by an alert by an FBI canine team. That was used as the basis for obtaining another search warrant and that search was ongoing as of 8 p.m.
