The search for a missing 6-year-old Arizona girl who authorities say may have been snatched from her bedroom in Tucson entered its third day on Monday as search dogs shifted investigators' attention back to the child's home.
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 were focusing on Monday on the interior of the home itself, Tucson Police Chief Roberto Villasenor said.
Two specially trained dogs brought in by the FBI arrived on the scene late on Sunday, he told a news conference on Monday morning, and "the dogs did alert on a few things ... but what exactly that is 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. And we will conduct that follow-up investigation."
