Police are reviewing hours' worth of surveillance video taken near Isabel's home around the time she was reported missing, Sgt. Maria Hawke said at a news briefing Tuesday.
Meanwhile, the 911 call to police the day Isabel disappeared continues to be withheld from the public. It will be released after police remove some of the information in the call, Hawke said.
Friends and co-workers of Isabel's mother, Becky Celis, who is a Tucson Medical Center nurse, are asking for help in manning the makeshift volunteer center in the shopping center parking lot on the southeast corner of South Craycroft Road and East Broadway. More than 250,000 fliers have been distributed in the Tucson area and in Nogales, Ariz. The center is open daily from 8:30 a.m. to 7:30 p.m. For more information, send an email to email@example.com
On Friday, Boston Market at North Tanque Verde and East Grant roads will donate 15 percent of your total purchase to the Isabel Celis Fund if you mention the child's fundraiser from 11 a.m. to 9 p.m.
More than 1,000 tips have been reported. Isabel, 6, was reported missing from her midtown home April 21.
