PHOENIX -- Search teams and dogs spread out through a park in San Antonio Thursday, looking for missing baby Gabriel Johnson of Arizona.
"Cadaver dogs searched the park but did not get a hit on anything," said the child's father, Logan McQueary.
The search comes as the kidnapping and custodial interference trial against Gabriel's mother moves forward in a Phoenix courtroom.
It's unclear what kind of tip prompted the new search for Gabriel, or who it came from.
The head of the Alamo Area Search and Rescue says four handlers and four dogs spent three hours searching a rocky, wooded park in the northern part of San Antonio Thursday morning.
"It's a rocky, wooded area. The dogs are specifically trained to locate human remains," Christy Bormann told 3TV.
Bormann declined to comment further about the connection between her team's search and the missing baby case.
San Antonio Police did not return calls.
