AS3.0 :: Make An Object Vanish In Flash CS4?

I have a question on how i can remove an object when two objects hit.I have two objects on the stage overlapping.

object #1 = character_mc
object #2 = vanish_mc
 
I want to make it so that the object #2 (vanish_mc) will vanish once i run it.
 
I have this code:
 
this.addEventListener(Event.ENTER_FRAME, vanish);
function vanish(event:Event):void{
if(character_mc.hitTestObject(vanish_mc)){
// here the code to remove vanish_mc from the stage
};
}
