ok =] i can almost be helpful here
In our town high school, there is a club called S.A.D.D. its Students Against Drunk Driving. they make HUGE posters and hang them all over the school. one of the gigantic posters hanging in the lunchroom was someone in a black cape thing with a black hood on to represent death, and they drew a tombstone, and had the dead person's 'friends' sign it saying things like 'sorry i didnt stop that last drink you had' and 'sorry i didnt try to take the car keys from you' (my brothers went there last year and 2 years ago, so i went there a lot) . MANY similar posters hang in the gym theater etc. on one day a year, they have the members dress up in black and walk around the school to indicate the dead teenagers. while they are walking, other members make up stories about how they died and how everyone felt. they use their peers' names so it has more affect.
hope i helped =] good luck
