The reward was announced Friday by a New York-based security consultant for television networks. Bill Stanton says the money is coming from anonymous sources. He refused to provide details or say who hired him.
Lisa Irwin's parents reported her missing Oct. 4. They say she disappeared from her crib overnight as her mother and two brothers slept.
Stanton says the logistics of how the reward would be distributed haven't been determined.
A spokesman for Kansas City's TIPS Hotline says it hasn't been contacted about the reward. The nonprofit hotline overseen by Kansas City authorities has been fielding hundreds of calls on the case.
