TUCSON - On February 18, 2007, the decomposed body of 4-year-old Ariana Payne was found inside a bad, in a Rubbermaid case inside a storage unit. Her 5-year-old brother Tyler would never be found.

Michael Orozco, a former TPD detective, was the lead detective on the case. We sat down with him to get his perspective on the case of 6-year-old Isabel Celis. Police are now treating her disappearance as a possible abduction, a type of case Orozco is quite familiar with. "In abductions especially, you need to move quickly, be as thorough as you can, because time is of the essence," said Orozco.

The big question everyone wants to know the answer to, what happened? Orozco says good detective work, evidence and real facts are the only way we're going to know. "You want to find this little girl, any little girl, as quickly as you can, and move toward a successful conclusion."

With candlelight vigils and an entire community praying, the best advice according to a former detective with nearly three decade's experience, is always remain optimistic. "Children have been found years and years later. But they've been kept by their abductors, and kept hidden. We've seen that over the last couple of years in the media, so there's always hope," said Orozco. "More than anything else law enforcement wants to find this little girl, and they want her to be brought home safely, and put back with her family."
