PHOENIX -- For the first time since a Tucson girl disappeared from her home five weeks ago, officials have released more information on the case.
The Tucson Police Department has just made public some 550 pages of documents related to the investigation. They include reports filed by officers in the search for Isabel. The documents reveal some of the evidence that has been seized, including blood from the family's home.
Investigators believe Isabel disappeared from her bedroom sometime after 11 p.m. on Friday, April 20. Her parents say they tucked in her that night only to find her gone the next morning.
The screen had been removed from her bedroom window. Forensic detectives apparently found and photographed footprints and shoe impressions in a nearby alleyway. One report indicates police found blood on the floor in the house.
Investigators also seized evidence from a car parked at the Celis home. Among the items, a white hat and vinyl shower curtain. Reports indicate the items had "dark red-brown or brown stains." Tests were not preformed on the shower curtain because detectives wanted to keep it as close to its original condition and allow crime-lab personnel to screen it if necessary. Another officer reported a positive result in testing traces of blood in the driver's seat.
On the morning Isabel was reported missing, police immediately took DNA samples from the child's parents and brothers. According to documents, they also took the Isabel's hairbrush and toothbrush.
More than 1,000 tips have come in so far. One caller reported a pair of children's sandals found in a garbage can. Those sandals collected as evidence.
To date, hundreds of officers have been involved in the search Isabel. The investigation has cost the Tucson Police Department more than $1 million.
No suspects have been named in Isabel's disappearance, but police are not ruling anyone out.
