Police Chief Greg Suhr says his department is following every lead in the case.
"We're getting help right now from FBI on some of the technical work that we're doing. We're very hopeful that we're going to get a break. God willing we will find little girl alive," Suhr said.
The toddler hasn't been seen since February.
