I agree; this statment is out of context. I assume it means that Kate wants her visits to keep Madeleine in the spotlight.

I'd really need to see the rest of the paragraph to give you a definite answer. However, it could mean what you said or it could mean that once Madeleine was missing, her mother was intent and focused on informing the entire world of her daughter's situation (that she was a missing child).
