Lt. Fabian Pacheco said detectives wanted to talk with the group walking early in the morning to see if they had seen anything unusual. Pacheco didn’t say at a press briefing Sunday afternoon what the men and women told officers.

“Please, please — to the person or persons who have Isa, tell us your demands,” said her father, Sergio Celis. “Tell us what you want. We will do anything for her.”

Isabel was reported missing from her family’s home Saturday morning. She was last seen by family members when she went to bed at 11 p.m. Friday, and a screen was found removed from one of the home’s windows, according to Tucson police.

Isabel was reported missing from her family’s home Saturday morning. She was last seen by family members when she went to bed at 11 p.m. Friday, and a screen was found removed from one of the home’s windows, according to Tucson police.

Because those first 48 hours are considered crucial to survival, there is reason for concern in the case of 6-year-old Isabel Mercedes Celis, a missing Tucson girl whose case has triggered national interest. She was last seen by her family at 11 p.m. Friday.

Police have categorized Isabel’s disappearance as a possible abduction after finding a broken screen on her bedroom window. Police have contacted all 17 registered sex offenders who live within a 3-mile radius of the home, officials said.

The parents of first-grader Isabel Mercedes Celis told detectives she was last seen on Friday night when they tucked her into bed, and was found to have vanished when a family member entered her room the next morning to awaken her, police said.

After an intense but fruitless door-to-door search of a 6-mile-wide swath of Tucson surrounding the girl’s house over the past two days, investigators renewed their focus on the interior of the home, this time with the family removed from the residence, Tucson Police Chief Roberto Villasenor said.

Two specially trained dogs brought in by the FBI arrived on the scene late on Sunday, Villasenor told a news conference, and “the dogs did alert on a few things … but what exactly that is what we’re trying to determine.”

“We have information obtained from the dogs that necessitate our follow-up investigation,” the chief said. “In order to do that, we secured the residence. We’ve asked the family to leave the residence so we don’t have to talk about any other contamination of the scene.”

Police extended their search to adjacent neighborhoods and were scouring a nearby landfill for clues on Monday, a move that Lieutenant Fabian Pacheco, a police spokesman, described as routine “in these types of investigations.”

Police have said they were treating Isabel’s disappearance as a “possible abduction” and that they were not ruling anything out and have not identified any suspects in the case.

Villasenor said family members had been cooperating with investigators, but he declined to discuss their current whereabouts or say whether any had taken a lie-detector test.

The 5th Annual Water Safety is for YOU! Event will take place at the Edith Ball Aquatic Center on April 24 from 9:30 a.m. to 1:10 p.m. Students will visit stations that re-enforce the drowning prevention messages they’ve learned in the classroom.

Safe Kids Tucson and community partners have been working together to raise awareness about drowning prevention, including the simple and consistent “ABCs of Water Safety” message: Adult supervision, Barriers around the pool, and swim and CPR Classes.

Arizona ranks second in the nation for child drownings, and last year, there were 18 water incidents in Pima County, including seven fatal drownings – five of which involved children.

News 4 Tucson’s Kristi’s Kids is taking part in the effort to prevent drowning incidents this year with the Lifesaver program.

American, which has operated the center here since 1991, says reservations representatives will be offered transfers to other centers or jobs as home-based representatives.

“We will avoid offshoring and preserve those jobs by offering employees the chance to transfer to other offices or become home-based representatives, just like the 150-some home-based representatives already in the Tucson area,” American spokesman Bruce Hicks said in prepared remarks.

The timing of the closure is unclear, and American officials didn’t respond to a reporter’s queries Wednesday.

A company spokesman said recently that the Tucson center employed 719 as of Feb. 1.

American and parent AMR Corp. filed for bankruptcy protection in November. AMR lost $2 billion last year, including restructuring costs, and has lost more than $10 billion since 2001.

The Tucson center closure is part of a larger plan to eliminate 1,200 nonunion jobs companywide as it cuts costs while under bankruptcy protection.

That pushes the company’s overall job-cut target to 14,200. It announced plans in February to cut 13,000 union pilots, flight attendants and ground workers, and make other cost reductions designed to slash annual labor costs by $1.25 billion.

American, based in Fort Worth, Texas, is the nation’s third-biggest airline with about 73,000 workers.

The changes for agents and similar employees are expected to save $95 million, which American said would match 20 percent cost-cutting targets for all other labor groups.

More than 5,000 people work in Tucson’s call-center industry, and the local industry has been expanding in recent years.

The pending closure of the American Airlines reservation center has little to do with the local economy, said Laura Shaw, senior vice president of marketing and communications at Tucson Regional Economic Opportunities (TREO).

Other call centers expand

In fact, several call centers have expanded their operations in Tucson or located new centers in the area since last July, she said.

They say Alaska Airlines, which is part of Alaska Air Group Inc., was responsible for the largest increase, having served 32 percent more passengers at the airport in the first quarter.

Starting in June, Alaska Airlines is scheduled to use airplanes with 18 percent more seats for its daily flights between Tucson and Seattle-Tacoma.

American Airlines, which is part of AMR Corp., flew 17 percent more passengers in the first quarter and Delta Air Lines’ volume went up 6 percent.

They say Juarez-Orci allegedly forced his way inside home of his wife and attacked her with a deadly weapon on April 5. Police say the couple wasn’t living together and Juarez-Orci’s wife had an order of protection against him.

The woman and the couple’s three children ran to a neighbor’s house to call for help. Authorities say the woman was taken to a Tucson hospital and treated for non-life threatening injuries.

When she was brought to HSSA in February, Dahlia weighed less than 30 pounds. The small plastic honey packet and pieces of asphalt in her stomach were evidence of her suffering. Dahlia has come along way. She has now gained enough weight and strength to be ready for adoption.

Amazingly, other than weak hips, Dahlia doesn’t appear to have any long-term health problems. She has nearly doubled her weight, and enjoys walks and playing fetch. She gets along with dogs and older children.
