Saturday marked one month since 6-year-old Isabel Celis was reported missing from her Tucson home.

Isabel was last seen getting ready for bed in her midtown Tucson home April 20. Her parents reported her missing the next morning when she was not in her bedroom. A window was later found open with the screen pushed aside in the family's home.

Friends of the family and volunteers said they have passed out hundreds of thousands of fliers since the girl vanished in hopes of generating leads. (Click here for a printable flier.)

Last week,  Tucson police Sgt. Maria Hawke said Isabel's had previous contact with Child Protective Services.

Hawke would not get specific about the details, but said CPS had been involved with the family months before 6-year-old Isabel Celis disappeared.

The girl's father, Sergio Celis, was prohibited from contact with his two older sons after detectives called Child Protective Services recently with information regarding the welfare of the older Celis children.

Authorities have stressed that doesn't mean he is a suspect in her disappearance.

CPS said its involvement is common practice when investigating cases of missing children.

Tucson police also announced last week they are classifying Isabel's disappearance as an abduction after investigators determined the girl didn't leave her home alone and they reviewed the evidence.

At an afternoon news briefing Thursday, Hawke said law enforcement assigned to the case are diligently pursuing "quite a bit of investigative activity."

"Whether it's stranger abduction or someone known to the family, both are being investigated," Hawke said.

Hawke said 20 detectives and 30 support personnel continue working the case.

"We haven't come across any signs that indicate that she's not alive," Hawke said.

On Monday, police released 911 calls after Isabel vanished. In one of the calls, the father of Isabel tells an operator that he believes his daughter was abducted.

The first-grader is described as just under 4' tall and weighs 44 pounds, with brown hair and hazel eyes.

Anyone with information about the whereabouts of the girl is asked to call 911 or 88-CRIME.
