Police putting pressure on couple in Baby Gabriel case, Wisc. blogger says she has child

Posted: Updated:

TEMPE -- It's been weeks since an 8-month-old Tempe baby disappeared and now new details are emerging about where he might be.

Yesterday, a woman from the Midwest blogged about adopting a baby named Gabriel in San Antonio. Investigators are following up on that, but have not yet been able to confirm anything.

Back here in the Valley, police are putting the pressure on a couple they consider persons of interest in thee case -- Jack and Tammi Smith, who claimed they were trying to adopt Gabriel.

Last week, the police called the Smiths people of interest, believing the couple knows more about Gabriel's whereabouts than they've said.

Investigators spent hours with Tammi yesterday. Late last night they served a search warrant at the Smith's home in North Scottsdale.

In addition to the blogger who claims to have the baby, another woman has come forward, saying she took care of the child a few days before she vanished.

The woman, who lives in Texas, says she babysat Gabriel in a Texas hotel. She spoke with CNN's Nancy Grace about Gabriel's mother, Elizabeth Johnson.

Johnson is behind bars here in Arizona. She's charged with kidnapping and is being held on a $1.1 million bond.
