AS3 mc removing from itself problem (...again)

Hi, i know there is many posts about this problem, but i haven’t solved my problem yet. Maybe is because i’m thinking in a wrong way and i haven’t understood AS3 concept yet…

My problem is the following:
I was programming games in AS2 in a way where movieclips could themselves remove, for example, when they collide whit main character.
If the objects where created in realtime with attachmovie then removeMovieClip, but if they where objects that where already existing because placed in the timeline, unloadmovie () was working.

I know in AS3 i can delete them from the parent who created them but, most of my movieclips are thrown into a frame in the main clip editor. I mean, i use the timeline frames as level editor where i design my levels and i place the objects directly there and not create them by code.
How can i remove them??
