TUCSON (KGUN9-TV) - Tucson Police have rejuvenated the search for missing Isabel Celis, and they are starting where it all began -- the neighborhood.
Fifty officers, including new detectives, flooded the area Wednesday looking for any clues they may have missed in the last two years, or any new information someone left out.
"A child doesn't go missing without somebody having seen something occur, that they haven't heard something about it, or that there's somebody out there who did it who told somebody else," Lt. Elise Souter said.
Police have set up a command post in the area. Officers will go door to door, re-interview neighbors and "take a fresh look" at the case, according to police.
By Thursday, the second day of the revamped search, police say new leads have once again poured in. Detectives are currently looking into said leads.
"I remember when they came and knocked on our door and asked us questions about it," neighbor Rick Haddock recalled. "I didn't think it had been two years already."
Tucson Police say the search is not based on any new leads, rather, they are trying to get a fresh perspective on the case.
"Hopefully that means they're seeing everything with a different perspective -- a different look -- which means that they can catch something that might have been missed," Isabel's mother Rebecca Celis said.
Police plan to scan the area of Broadway Boulevard and Craycroft Road from 12:00 p.m. to 10:00 p.m. every day until they've spoken to every household.
Celis, who was 6-years-old at the time of her disappearance, was originally reported missing from her east side home on April 21,2012.
She was last seen by her family late in the evening of April 20, 2012. If you have any information on her whereabouts, please call 911 or 88-CRIME.
