Urgent: Amber Alert ??? Is it real?

My husband just received an Amber Alert.  2 little girls kidnapped around noon, near Harrison, Arkansas area.  Suspect driving brown jeep liberty.  Kansas plates # 436519. 

Don't know if this is real or not.  Have been contacted and told it was a hoax.  It might be.

I just hate this.  It is my greatest fear!!!!!!!!!!!!
