Tucson Police say they are continuing their investigation into the suspicious disappearance/possible abduction of Isabel Celis, 6, who has now been missing from her midtown home for one week.
At a press briefing on Saturday afternoon, Tucson Police Lt. Fabian Pacheco says they have been receiving about eight to ten tips per hour in the case.
Pacheco says analysts continue to pour over tips that have been coming in from the public.
Pacheco says at least one person has come forward, to say they are one of five people seen in a surveillance video that was released to the public on Friday. Detectives say they will be talking to him, to see what information he is able to provide in the case.
Pacheco says they are looking at all options, and not focusing on any single source.
"This isn't CSI: Tucson, where we're going to solve this in an hour."
Ultimately, police say, they are not at liberty to answer a lot of the "hard questions" in the case.
Pacheco says the Celis family continues to cooperate with investigators.
A reward in the case has increased to $50,000.
Anyone with information is urged to call 9-1-1 or 8-8 Crime.
