Police: Father was alone with missing Tucson girl

TUCSON, AZ - Authorities say the father of a missing Tucson girl was alone with her when she disappeared. But police say that doesn't mean he's a suspect.

Authorities have been searching for 6-year-old Isabel Mercedes Celis since she was reported missing the morning of April 21.

At a news conference Monday, Tucson Police Chief Roberto Villasenor says investigators have confirmed that the girl's mother went to work that morning and Sergio Celis later reported Isabel missing from her bedroom.

Police also released the 911 calls from the morning. The first came from the father who described nothing out of the ordinary the night before she disappeared.

Sergio Celis is heard on the 911 tape saying, "They all went to bed and I was even up late watching the Diamondbacks game at midnight and I fell asleep and I never heard anything weird and I was just on the other side of the wall from her."

Sergio Celis' wife and son also called 911. They too did not report hearing anything.

Authorities are now prohibiting the man from having any contact with his other children. But police say Sergio Celis voluntarily agreed with Child Protective Services to stay away from Isabel's two older brothers.

Villasenor says the boys are staying with their mother.

Authorities declined to provide further details about Sergio Celis' status.
